Description

[Technical Field] The present invention relates to a circuit and method for transmitting and receiving digital data transmission signals, and more particularly to a framework for inserting, compressing, copying, transmitting and restoring digital data transmission signals. Circuit and method. [Prior technology] In the current situation, the Federal Communications Commission (Federal communications

The Commission, FCC) allows for the use of industrial-, scientific and medical radio frequency bands (ISM radi〇band) at 915ΜίΙζ, 2.442 GHz and 5. 750 GHz for type-approved and unlicensed use of shared and low-level owners ( Uniicensed uSe), the configuration of this radio wave spectrum is insufficient for increasing spread spectrum communication. In fact, the focus is that the configuration of this radio wave spectrum is a shared state, and other users appearing on these ISM bands or Other signals are not fixed frequency or spread spectrum, which may cause radio frequency (RF) interference. ... Radio frequency interference is because the unwanted radio frequency signal occupies the same frequency as the original used signal, which will cause loss of information-sound or digital data. The key factor is that the degree of radio frequency interference is the original signal used. The strength and the strength of the interference signal, the interference signal occupies the bandwidth of the original used signal, and the interference signal occupies the bandwidth of the original used signal. The relative signal strength basically depends on the radio frequency common channel (co-channel) selection specification (selectivity specification); when the frequency hopping spread spectrum (FHSS) transmission system occupies the fixed frequency transmission system, the 'interference signal' The length of time that the bandwidth of the original signal is used is determined by the frequency hopping spread spectrum transmission system. Since these ISM radio bands do not require authorization, fixed-frequency applications such as wireless network solutions, radio frequency identification tags, alert systems, security monitoring, automated homes, garage door launchers, automatic meter reading The automatic meter reading, remote sensor and digital sound transmission; the same frequency hopping spread spectrum application on the ISM band includes digital wireless networks such as Bluetooth networks, radio and microwave telecommunications. These fixed frequency applications divide the ISM radio band into several channels 1324451 or subbands. Each fixed frequency should be separated from the specific channel or sub-frequency (4) application. The frequency hopping spread frequency subdivides the ISM non-band into several channels of the same but smaller bandwidth. , j_ will only occupy each channel for a short time, and the frequency hopping spread spectrum application will jump from one channel to another in a specific frequency hopping mode such as virtual random number hopping mode, which may be pre-generated with a fixed frequency system. If it continues for a period of time, it will cause the application to be interrupted. Taking the Bluetooth specification as an example, it divides the ISM wireless band into 79 channels with i-hidden bandwidth. The blue-through specification allows the transmitter to perform 1600 frequency hopping operations per second. If a fixed-frequency application cuts the ISM band into 1 channel, a Bluetooth transmission will be based on this fixed frequency band 6. 25 microseconds, which will create a distortion or error situation.

The requirement is a new transmission data rate multiplication factor and a new data frame length group number. The source of the interference is a Bluetooth adaptation source (Bluet00廿j compiiant source) or a cordless telephone. The details of the present invention, the technical content, the features, and the Efficacy [Implementation]

In the fixed frequency communication system of the present invention, the transmitter needs digital data such as digitized sound that is converted into data frames. The transmitter (i±e transmitter time) compresses and copies these data frames based on a compression factor (c〇mpressi〇n fact〇r). The multiplicati〇n factor of the data transmission rate depends on the data transmission rate (transmissi). 〇n乜乜mte) How fast and thus increase the agrouping of frames to avoid interference from the frequency hopping spread source (fhss interfering source). The multiplication factor of the data transmission rate increase is at least two times and can be any multiple. By changing the number of data transfers before copying, the department can adjust the frequency hopping spread spectrum interference source to send the largest job. After the data frame of the job copying is transmitted, it is transmitted to the receiver through the air, and the receiver will restore the digital data that has been pressed. The number of the digits after the copying of the numerator (4) is the digit that will be copied in the Utomge digital storage path in the storage digital circuit. The data is taken out and the digital data is copied out, and the data is damaged. If the digital data is not damaged, then (4) will continue to process, but if the data has been damaged, the frame will be retrieved from the age digital circuit. And step-by-step to verify whether the data is corrupted ^ If the data frame is copied and: If it is bad, then these data frames will be added to the main replication material frame ^ = rephcated data frames) and marked as normal (g〇〇d) The group transmits the core into the Wei-step process. (4) Bellow frame In the embodiment of the digital sound system, the digital data is presented through the encoded data 12 1324451 frame. If multiple copies of the digital data (all of the four (four) are damaged, the sound processor An error message will be generated and the sound transmission or advance will be turned off to provide the value of the customer to the missing t_frame to correct the corrupted data frame.

The problem solved by the time compression (compression) and diversity communication systems in the present invention will now be explained with reference to FIG. The RF spectrum of the document control as described above, such as the US Federal Communications Commission, specifies the frequency band 5 in the spectrum as a special use. In the case of the isM band, unlicensed and many different forms of applications appear in this band. The allocated frequency band 5 is further divided into a plurality of sub-bands and channels l〇a, ..., l〇n, and i5a, ..., 15n, ..., 15z. In the allocated RF band 5, the number of channels depends on the bandwidth required for its application.

In a frequency hopping frequency application, the number of channels determines the probability that a particular subchannel is occupied at any point in time; the hopping rate in a frequency hopping spread spectrum application determines the time at which the subchannel is occupied. In fixed-frequency applications, the channel is always occupied as long as the transmitter continues to transmit signals. Therefore, if there is a frequency hopping spread spectrum source and a fixed frequency signal source close enough, the frequency hopping spread spectrum source will be intermittent interference 疋 frequency source 'this will be enough to destroy the fixed frequency signal source Signal sent. For example, if the RF is configured with the frequency band 5 simultaneously by a fixed-frequency application i〇a,..., ι〇η and a frequency hopping spread spectrum application 15a,...,15η,...,15z, and the fixed frequency application i频a,...,Wn's bandwidth requirement factor(n) is greater than the frequency hopping spread spectrum application 15a,...,15η,...,15z,, then the frequency hopping spread spectrum application 15a,...,15η,...,15z is used by fixed frequency applications The time of i〇a,...,ι〇η interference can be represented by this formula:

Where: ti is the interference time nwf is the difference factor (differential factor) or the frequency hopping spread spectrum application 15a, ···, 15η,...,15z and fixed frequency 10a,...,l〇n. Pr(ch)—a frequency hopping spread spectrum application channel 15a,...,15η,...,15z is given at a time between 1324451 and given in the RF configuration band 5 for frequency hopping spread spectrum applications 15a,...,15η,...,15z After the number of countdowns used, its probability of being occupied fh is the hopping frequency of the frequency hopping spread spectrum application 15a, ·.., 15η,...,15z (for example: Bluetooth application is 1600 jumps per second) From the above formula can Seeing that the frequency hopping spread spectrum applications 15a,...,15η,...,15z have more channels used in the RF configuration band 5, the fixed frequency application i〇a,...,ι越η will be less

It will be disturbed, but it will still happen. Furthermore, the lower the hopping frequency, the frequency hopping spread spectrum applications 15a,..., 15η,...,15z will stay longer on a particular channel and the more likely they interfere with the full frequency communication. Referring to Figure lb, a digital audio signal transmits a series of audio frames 2 随着 over time. Each sound data frame has a duration xt during which minor interference signals can be corrected by embedded error correction codes. However, if a frequency hopping spread spectrum signal 25a is transmitted on a frequency hopping spread spectrum channel that is repeatedly covered by the fixed frequency signal channel, the frequency-divided signal will be interfered with by the frequency hopping spread spectrum signal for a period of time. During the period, the frequency hopping spreader will transmit the (four) channel. The dry shot can be extended to the same time - a fixed fresh ship towel __ ship_ road, or may interfere with the lamp for a period of time after any time interval τι?Α_.

The track in the present invention is suitable for digital sound data transmission of a digital sound source, for example, a multi-player player-digital sound device. According to the current technology, the "digital" method uses the continuous discrete time interval of the sound signal to determine, take, and read the sample value into a uniform spatial image that is pulse code modulation tir = er- duiatiGn, ραο +_余. The number of scales is formatted: it is binarized and added to the data frame to construct a two-start (start symbol) 40 frame. The error correction code 45 is - a forward error #不The first m ^ doctor added to the tribute material group 30 to correct the outside _ Xt traits 1 positive coding, he allowed the correct voice to correct the code I, the object __ in the error 14 1324451 each data frame 20 represents the sound and must be in The time is encoded and decoded to maintain the frequency of the audio stream. The transmission time of the data frame 2 is transmitted through a copyable data frame (four) wire (the frame rate of the reduced frame (4) will be increased or accelerated) For example, if the multiplication factor of the transmission data rate is 2, then the data frame 20 will be made twice. By analogy, if the transmission data rate multiplication factor is 3, the data frame 20 will be copied three times. Through the copying Before the material frame, a series of data frames can be grouped to determine how much time is allowed to avoid continuous interference in the given time Yt. Changing the grouping of the data frame affects the waiting time caused by the processing time during sound playback. Latency. However, it maintains the frequency of the sound playing stream. In the communication system of the present invention, the time interval Yt. must be large enough to avoid all the frequency hopping spreads from the fixed frequency channel in the time interval. Interference from the signal source. Refer to Figure 3a' for a fixed-frequency transmission source assigned to the channel 1〇5 of the rf configuration band 1,. The frequency hopping spread spectrum interference source will be on the channel overlapping the fixed-frequency transmission source. Transmission, like the radio frequency of the fixed-frequency channel bandwidth is the same as the bandwidth of the frequency hopping spread spectrum channel, so the fixed frequency channel will contain a certain number (m) of the frequency hopping spread spectrum channel at the same time point 'virtual chaos The pseudo-random frequency hopping will cause the frequency hopping spread spectrum channels to be occupied sequentially. Or the time when the fixed frequency transmission is disrupted by the frequency hopping spread spectrum transmission is the maximum of the multiple m times the frequency of each hopping frequency. Tao The number of replicated data frames on the time-frequency fixed-frequency channel is 120. The single data frame is multiplied by the multiplication coefficient of the transmission data rate. The next frequency-hopping spread-spectrum interference source will interfere with the highest number of data frames of the fixed-frequency transmission source. The coefficient is a fixed coefficient in the presence of interference and is represented by the following formula: TDRMF = factory n Eq. 2 where: TDRMF is the transmission data rate multiplication factor "is the next largest integer (upper limit ) tframe β 15 _ Nf is the number of data frames in the data frame length grouping number when two = iS: 』Wlnd〇W), and is the duration of the data frame.

The error correction code generator 220 generates a forward error correction code added to the serialized frame frame 'frame interleaving circuit' for a data frame. The having pattern to minimize the loss of the frame, y, / ring and allow the ability to soft muting and interpolation in the two data frames in the sound application. To the time diversity circuit 230, the time diversity circuit 230 includes a time compression circuit 235 that compresses the data frame 'time compressed data frame based on the previously transmitted data rate multiplication factor in a frame duplication circuit 240. Being replicated and serialized, the time diversity circuit 230 then transmits the data rate and the data in each replicated group. The number of frames is added. The serialized 'compressed and copied data frame is transmitted to the transmitter's signal modulator 245, and the transmitter's signal modulator is synchronized to the synchronizing clock circuit 275. To the fundamental frequency F. , then the fundamental frequency F. As the serialized, compressed, and replicated data frame is modulated, the modulation technique can be any known amplification, frequency, and now known phase keying modulation techniques. The φ modulation base signal is transmitted by a transmitter driver 250 and is driven from the transmitter driver through an antenna switch 255 to drive the antenna 265 to transmit the modulation signal 160 to the atmosphere, and at the same time, the frequency hopping spread spectrum transmission source 150 transmitting the frequency hopping spread spectrum signal 150 may interfere with the modulation signal. The antenna switch 255 is set in the transmission mode during the transmission of the modulation signal, and is set to the reception mode when receiving the interference hopping spread spectrum signal 150 or any interfering fixed frequency signal to determine which channel can be transmitted, and the interference hopping The frequency spread signal 150 or the interfered fixed frequency signal interferes with the antenna to generate an interference signal that is transmitted to the interference receiver 260. Fundamental frequency F. 285 is the transmission interference receiver, the fundamental frequency ρ. The 285 is used to capture the interference hopping spread spectrum signal 150 or any fixed frequency interference signal. The recovered frequency hopping spread spectrum signal 150 or the interference evaluation circuit (interference evaluation circuit) is evaluated as a fixed pinch signal number, then the dry B# is wrong (four) 97K, and the channel switching signal is sent to the synchronous clock circuit 275+, and the synchronization is performed. Gu (four) test j / 丨 ^ change the fundamental frequency F. 285 to another channel; the interference evaluation circuit 270 is rated as a wrist to determine whether its feature conforms to the frequency hopping spread spectrum interference signal, and if it is a 'spreading frequency signal, it is characterized by a hopping pattern, each -^ The time between the hop, the total transmission time, the transmission god relative to the expected received power, and the transmission bandwidth between the primary hops. Broadcasting (10) Sunrise loses money for the skipping frequency interference 150, the special features of the frequency-frequency spread surface V 1 will be evaluated to determine the time interval of each channel and the data according to the former η cow type The number of frames is determined by Yt, and the compression factor is also transferred to the synchronous clock circuit 2?5, which is typically 2. The modulation signal 160 of the ^^^305 is interfered with the frequency hopping spread signal 150 or any dry = estimated vt', as indicated by the sixth ride, which is made in the fourth (fourth) period. The input signal source is broken from the antenna switch to the receiver input circuit (a lver i 叩 potential and a regulator circuit 312 for amplifying the modulation signal or demodulating the signal. Circuit 312 transmits the received signal. The signal is sent to the interference assessment circuit 350, the second signal, or the desired signal or the main source of the frequency hopping fresh signal (10) or the interference signal source. ^ It is a fixed frequency interference signal, amplifier and adjustment In addition, the feedback transmitter (feedback transmitter) moves to request a new, 'personal route, send a new modulation signal (10) 'return transmitter to activate the antenna switch to connect ^ feed transmitter 355 to,] antenna 305, feedback transmission The transmitter transmits a request to use the new channel to transmit the signal 16G, ___ a clean_channel is obtained, and the modulation signal 16 (| is then received by the amplifier and adjustment circuit 312. Right interference# The evaluation circuit 350 determines that the undesired signal is an interference hopping spread frequency = 150, and the interference frequency estimation circuit 35 〇 estimates the recovered 捿 signal to detect its characteristic 'feature: then the frequency hopping mode ( H〇pping pattern), every jump Frequency time interval, total transmission time 'Transmission of the work axis for the measurement of the reception turn and the transmission bandwidth between each-hop frequency, the restored interleaved 'compressed and copied digital data is transmitted to the start/stop power 1324451 ( The start/stop circuit 313 is used to decode the start symbol and the b clock circuit 314 from the digital data to unlock the sync block, and the start symbol and sync block are used for communication between the transmitter 200 and the receiver 300. The signal is transmitted to the diversity circuit 315, and the diversity circuit 315 captures the digital data of the signed and synchronized blocks. The diversity circuit 315 receives the interference from the interference evaluation circuit 350, and the diversity circuit uses the evaluation signal to resolve the transmission. The multiplication factor and the number of data frames in each replication group, the sender in the fourth group will use this number to compress and copy the data frame. The transmission data rate multiplication factor is positive for the communication system. The value is usually 2, but can be adjusted according to Eq.丨. The system adjusts the number of data frame length groups (data(10) than grouping) in the frequency hopping spread spectrum signal 150 to avoid jumping. The spread spectrum interference time. The diversity circuit 315 exchanges the buffer control signal 34 with the buffer 325 to organize and arrange the input data frame (4) position, and the copy of each teacher's bribe will be recombined with the appropriate sequence to 'collect each copy. It will then be grouped for fast access by the buffer. The buffer control signal 340 allows the necessary communication with the diversity circuit 315 and the buffer 325 to be configured in the correct order of the _(4) mind and the frame of the audible frame. In the diversity circuit 315, there is an error detection and correction circuit 33 to receive the information from the buffer to be revamped (she is red seHes), and the error correction circuit 330 estimates each data frame. Each forward error correction code in the data frame details whether the data frame has been corrupted or not, and the data frame of the first copy of the R1 towel is marked as normal and returned to the buffer 325. Frame R2 is not = stored back to buffer 325. If any major data frame replication error occurs, the data frame of the duplicate material frame R2 replaces the primary copy of the data frame, and each forward error correction code in each data frame is evaluated to detect whether the data frame has been Damaged, if there are no errors in it, the copy will be marked as normal as the first copy R1. If it does not have any other copies' and the data frame is judged to be wrong according to the inclination, then the data rejection frame It will be recorded as listening (enOr·), and the data frame will continue to accept the evaluation for errors.

In a digital sound application, the audio signal is converted to a sampled digital signal in step 44, and a digital audio signal is formed as described in step 445, and a one-way error correction code is generated as described in step 450 and Adding to the digital audio frame, the digital audio frame is then hashed as described in step 455 to avoid errors that cannot be inserted or completely turned off. The μ frame is grouped based on the number of data frame groups and the transmission data rate multiplication factor jTDRMF). As described in step 46, the number of data frames in each group and the transmission data rate multiplication factor are added to each data. In the header of the framework, the receiver will examine each data frame to recover the number of grouped data frames and the transmission data rate multiplication factor. In step 470, the 'data frame is copied and seriaUy streamed'. The number of data frames may be fixed to four but may also be any number to ensure that the data frame is not interfered with by the frequency hopping spread source. Destroyed. Furthermore, the transmission data rate multiplication factor is set to two to produce two copies for each data frame group, but the number of complexes may be any number, depending on whether the number of interferences from the surface spread spectrum interference source is allowed. The previous Eq. 1 finds that an RF signal is modulated according to a time compressed and serialized and transmitted copy data frame, as described in step 485. 8a and 8b are methods for receiving a fixed frequency modulated RF signal in the presence of a frequency hopping spread spectrum interference source, as described in step 5, a selected fixed frequency channel and a modulated RF signal. The received modulated RF signal is amplified and adjusted in step 51〇. 21 1324451 is changed to the RF signal to extract the modulated digital data, and then as in step 5i5 and the coffee == then the frame is then synchronized and then solved. Open, as step _ said, two fixed 3 2 153! / is evaluated to determine whether the received modulation signal is 535, receiving 'right - signal is a fixed frequency interference signal, then as in the step The receiving is to require the transmitter to change the fixed track to another RF modulated signal in the configured RF band to be received (as described in the step of amplifying and adjusting step 525 to unpack the data frame. Then, as in step 53 After i ^ β & Lai Dao Xian, the framework then proceeds to check whether the received RF telemetry source - a frequency hopping spread spectrum interference source, such as step _, the frequency interference source appears, the transmission data rate multiplication factor will be set to one (material = any multiplication), and select the minimum number of _ shelf groups For example, the step (10) frequency-frequent signal is a frequency hopping spread spectrum interference source, and if there are multiple frequency hopping step 550, the data frame in each group is taken from the header as determined by the step coffee. The size and position of the buffer, in this buffer. In step (10), the data frame will be in the order of the buffer, and in step 575, the data frame will be selected in the data frame. And from the data rush, as in step 580; the main copy of the ordered data frame has its own error, if you decide whether there is any damage during the transmission process, as described in step 585, the complex correction will be Correction, the corrected ordered data frame is mainly in the buffer 565, and then, as described in step 59, the data frame evaluates the positive error of rjf. If there is no error that cannot be corrected, then the frame of step 605 is _ Marked as normal 'and the other person's voice signal let or · ear _ put. If the conversion data ^ can not be corrected, then use the existing one of the existing order as described in step 295.

As described above, the re-generated sound signal has a maximum allowable delay time limit of 20 milliseconds, all digit conversion, code compression, time diversity replica (time diversity replicati), error correction, decoding and sound signals The re-conversion must be completed within this delay time. A major source of interference for the fixed-frequency communication system in the present invention is the well-known Bluetooth personal area network specification. The Bluetooth specification needs to operate on the ISM RF band and use the frequency hopping exhibition. The frequency method performs 1600 frequency hopping per second on 79 channels, each channel of the Bluetooth specification has a bandwidth of 1 MHz (measured value 20 dBc) and the frequency hopping order is a sector type virtual random number non-repeating code (segmented) In the communication embodiment of the present invention, the bandwidth of the channel is about 8 MHz, and the probability of the Bluetooth frequency hopping spread spectrum 23 1324451 interfering with the fixed frequency transmission of the system is 8/79, each blue The bud has used 79 channels for 49. 375 milliseconds. In the worst case, eight hopping sequences will appear on the 8 MHz transmission bandwidth of the communication system of the present invention. The eight consecutive occurrences in this bandwidth are 8*625 microseconds = 5 milliseconds. These transmitted data frames must be copied and placed separately for at least 5 milliseconds. This value comes from the 3a diagram. The digital data frames to be transmitted must replicated and placed at least 5msec apart which is the value of the time Yt 130 of Fig. 3a., in a system in which these replicated data frames are placed for more than 5 milliseconds, causing The probability of error will be: 8/79*7/78*6/77*5/76*4/75*3/74*2/73*1/72*0/71 = 0. This guarantees that there will be no Any errors are caused by Bluetooth interference. Although it is suitable to compress and copy these data frames to eliminate the frequency hopping spread spectrum interference signal, even if the time Yt 130 is set to -峨 small, the Wei Mai will also become a smaller value. An improvement under the compression and copying procedure of the invention is as follows: for example, if the time diversity is set to 2 milliseconds α 13 〇 and 5 milliseconds (Yt 130) ' 2 milliseconds respectively included in this transmission Three consecutive jumps that will cause errors (2/G. 625=3.2). The underlying conditions under such conditions are as follows: 8/79 * 7/78 * 6/77 * 5/76 = 4. 65 raft 5 means that every 17. 7 minutes will occur - an error, time Yt 13 〇 and the number of transmission data frames within the group can be balanced with the error rate to achieve the best design point (optimum Design point). Another - a hopping spread spectrum «from the wireless phone, in terms of the existing 颂 phone, its hopping frequency show method of hopping every 10 (10) hops on 90 parents, each channel has about 8Q_Z job And money with ___ (pseudQ Μ-code h0pping code) 'the probability of interference with the system in each frequency hopping cycle of the radiotelephone is 10/90 (every-radio phone jump ring time is _ milliseconds), The worst fixed-frequency transmission channel will contain ten consecutive hopping sequences, ten consecutive hops. The holding time is 1 〇1 〇 milliseconds = 100 milliseconds. In order to fully protect the transmission data, the sub-sequences in each block The periodic repeat time diversity Yt 13Q must be at least 24 1324451 100 milliseconds. This value is extremely large and the time diversity Yt 13〇 can be reduced. For example, 玎 is reduced to 30 milliseconds, 时间3a is the time diversity time Yt 13 〇 Contains three data frames with frequency hopping spread spectrum interference appearing on the continuous frequency hopping of fixed frequency channels (3〇/1〇=3). The probability of generating errors in such a system environment is: 10/90*9/89 *8/88*7/87 = 8.21X10-5 error rate is generated every three hours Error ((9-shaped 1 〇 milliseconds, again b 登'''''''''''''''''''''''''' The error rate is only the preferred embodiment of the present invention (4), and is intended to limit the present invention to the present invention, and thus the features and spirits described in the scope of the present invention are All of the four sides or modifications should be included in the scope of the patent application of the present invention.
