Description

The invention relates to the field of radio engineering, namely to radio transmitting devices that automatically adjust the parameters of the radio signal spectrum in order to ensure electromagnetic compatibility (EMC) with radio electronic equipment operating simultaneously with a radio transmitting device in common areas of space and in radio frequency bands of out-of-band radiation of a radio transmitting device.

A radio transmitting device [1] is known, consisting of a master oscillator having an output connected to one of the inputs of the multiplier, a pseudo-random signal generator having an output connected to one of the inputs of the multiplier, the output of which is connected to a baseband filter having an output connected to one of the inputs of the modulator, generator carrier wave having an output connected to another input of the modulator, the output of which is connected to the input of an amplifier having an output connected to the input of a bandpass filter, the output of which is connected to the input of the antenna-feeder device, which generates a BPSK signal and has a permanently tuned baseband filter that provides a reduced level of out-of-band radiation in the interests of guaranteed provision of EMC with radio-electronic means operating simultaneously with a radio transmitting device in common areas of space and in radio frequency bands of out-of-band radiation of a radio transmitting device.

- среднеквадратическое значение сигнала).The disadvantage of the known radio transmitter is that the use of a non-tunable baseband filter, focused on achieving a minimum level of out-of-band radiation of the radio signal, leads to a decrease in the efficiency of using the energy resource of the radio transmitter, caused by an increase in the value of the crest factor PF of the generated BPSK signal that has been filtered in the baseband filter , and, as a result, to a decrease in the level of the average power of the emitted radio signal (

, Where

- peak signal value,

is the rms value of the signal).

One of the possible ways to increase the efficiency of using the energy resource of a radio transmitter is adaptive dynamic control of the parameters of the spectrum of the emitted radio signal of the radio transmitter, depending on the results of monitoring the electromagnetic environment:

1) in the absence of signs of operation of priority radio facilities in the radio frequency bands of out-of-band radiation of the radio transmitter or if they are present, but the fact of the negative impact of the radio signal of the radio transmitter on the operation of the priority radio facility is not detected, the radio signal of the radio transmitter in the base band filter is not filtered, which minimizes the value of the peak- radio signal factor and increases the energy efficiency of the radio transmitting device;

2) when there are signs of operation of priority radio facilities in the radio frequency bands of the out-of-band radiation of the radio transmitter and the fact of the negative impact of the radio signal of the radio transmitter on the operation of the priority radio facility is revealed, the base band filter parameters are calculated based on the ratio of the signal power of the priority radio facility and the power of the out-of-band radiation of the radio transmitter, adaptation baseband filter to the emerging electromagnetic environment by restructuring its parameters to the calculated ones, and further filtering the radio signal of the radio transmitter in the tuned baseband filter, which causes a corresponding increase in the crest factor of the radio signal and a decrease in its energy efficiency.

In this case, if there are no signs of operation of priority radio facilities in the radio frequency bands of out-of-band radiation of the radio transmitting device or if they are present, but the fact of the negative impact of the radio signal of the radio transmitting device on the operation of the priority radio facility is not revealed, the energy efficiency of the radio transmitting device will be maximum. If the fact of the negative influence of the radio signal of the radio transmitter on the operation of the priority radio facility is revealed, the energy efficiency of the radio transmitter will decrease adaptively, based on the ratio of the signal power of the priority radio facility and the power of the out-of-band radiation of the radio transmitter, as a payment for providing EMC of the radio transmitter with priority radio facilities operating in the radio frequency bands its out-of-band radiation.

Thus, the purpose of the present invention (technical result) is to increase the efficiency of using the energy resource of a radio transmitter by adaptive dynamic control of the parameters of the spectrum of the emitted radio signal, depending on the results of monitoring the electromagnetic environment in the radio frequency bands of out-of-band radiation of the radio transmitter.

The achievement of the technical result of the invention is ensured due to the fact that the known radio transmitter [1] additionally introduced:

- a base band filter control device, consisting of a radio signal parameters determination unit, a radio receiver, a data block on the parameters of protected radio signals and a base band filter parameters calculation unit, which have the following connections: the input of the radio signal parameters determination unit is connected to one of the switch outputs, and one of the outputs of the block for determining the parameters of the radio signal is connected to one of the inputs of the block for calculating the parameters of the base band filter, and the other output of the block for determining the parameters of the radio signal is connected to one of the inputs of the radio receiver having an antenna input, an output connected to the block for calculating the parameters of the base band filter, and another input, which is connected to one of the outputs of the data block on the parameters of protected radio signals, having one input, which is another input of the base band filter control device, in the form of an X1 connector for connecting to a removable secure information carrier and another output connected to one of the inputs a baseband filter parameter calculation unit having one output, which is one of the outputs of the baseband filter control device, connected to one of the inputs of the switch, and the other output, which is one of the outputs of the baseband filter control device, connected to the input of the baseband filter. The baseband filter control device provides monitoring of the electromagnetic environment in the radio frequency bands of out-of-band radiation of the radio transmitter and calculation of the baseband filter parameters depending on the results of this monitoring;

- a removable secure storage medium connected via the X1 connector to the data block about the parameters of the protected radio signals and providing input to the base band filter control device of data on the parameters of the signals of the priority radio facilities necessary to monitor the electromagnetic environment in the radio frequency bands of the out-of-band radiation of the radio transmitting device;

- a switch connected between the modulator and the amplifier and blocking the radiation of the radio signal of the radio transmitter during the calculation of the parameters and the restructuring of the base band filter.

Elements of a radio transmitting device with automatic adjustment of the parameters of the spectrum of the radio signal have the following relationships with each other. The output of the master oscillator 1 is connected to one of the inputs of the multiplier 2. The output of the pseudo-random signal generator 9 is connected to another input of the multiplier 2, the output of which is connected to one of the inputs of the baseband filter 3. The output of the baseband filter 3 is connected to one of the inputs of the modulator 4. Output carrier oscillation generator 10 is connected to another input of the modulator 4, the output of which is connected to one of the inputs of the switch 5. One of the outputs of the switch 5 is connected to the input of the amplifier 6, the output of which is connected to the input of the band-pass filter 7, the output of which is connected to the input of the antenna-feeder device 8. Another output of the switch 5 is connected to the input of the block for determining the parameters of the radio signal 11.3, which is one of the inputs of the control device for the base band filter 11, one of the outputs of the block for determining the parameters of the radio signal 11.3 is connected to one of the inputs of the block for calculating the parameters of the base band filter 11.2, and the other output the block for determining the parameters of the radio signal 11.3 is connected to one of the inputs of the radio receiver 11.4, which has an antenna input, the output connected to the block for calculating the parameters of the base band filter 11.2, and the other input, which is connected to one of the outputs of the data block about the parameters of the protected radio signals 11.1, which has one an input, which is another input of the baseband filter control device 11, in the form of an X1 connector for connecting to a removable secure storage medium 12 and another output connected to one of the inputs of the baseband filter parameter calculation unit 11.2, which has one output, which is one of the outputs of the device control of the baseband filter 11, connected to one of the inputs of the switch 5, and the other output, which is one of the outputs of the baseband filter control device 11, connected to the input of the baseband filter 3.

Radio transmitting device with automatic adjustment of the parameters of the spectrum of the radio signal operates as follows.

The master oscillator 1 generates an electrical signal in the form of a sequence of information signal pulses and transmits this information signal to the multiplier 2.

The pseudo-random signal generator 9 generates one of the pseudo-random pulse sequences (spreading signal) for signals with various types of phase-shift keying BPSK signal ( BPSK , BOC , CBOC , TMBOC, DBOC, AltBOC, GBOC and NBOC ) and transmits the spreading signal to the multiplier 2. The choice of the type and parameters of phase keying is carried out by the controls of the pseudo-random signal generator 9 (not shown in the diagram of Fig. 1).

The multiplier 2 performs the formation of the resulting spread spectrum information signal pulse sequence x by modulo "2" addition of the information signal and spread spectrum signal pulse sequences, and passes it to the baseband filter 3.

The base band filter 3, having received at one input from the multiplier 2 the information signal of the spread spectrum x and at the other input from the block for calculating the parameters of the base band filter 11.2 - the command to turn the filter on / off and the value of the rounding coefficient of the frequency response of the filter α, forms a modulating signal y with the given characteristics of the spectrum and transmits it to the first input of the modulator 4.

The carrier oscillation generator 10 generates a continuous high-frequency harmonic signal with specified parameters and transmits it to the second input of the modulator 4. The parameters of the high-frequency harmonic signal are set by the controls of the carrier oscillation generator 10 (not shown in the diagram of Fig. 1).

- полосы внеполосного излучения сигнала (см. фиг. 2), который передает в коммутатор 5.Modulator 4, having received the modulating signal y from the baseband filter 3 and a continuous high-frequency harmonic signal from the carrier waveform generator 10, generates a BPSK signal with the occupied frequency band

, Where

- the main frequency band of the signal,

- bands of out-of-band radiation of the signal (see Fig. 2), which transmits to the switch 5.

The switch 5, before receiving from the block for calculating the parameters of the baseband filter 11.2, the codegram with the command to allow the broadcast of the BPSK signal to the amplifier 6, sends the signal received from the output of the modulator 4 BPSK signal to the block for determining the parameters of the radio signal 11.3.

The block for determining the parameters of the radio signal 11.3 performs quantitative estimates:

1) the parameters (center frequency and bandwidth) of the baseband of the signal and the bands of the out-of-band emission of the signal and transmits these estimates to the radio receiver 11.4 to monitor the electromagnetic environment;

2) the power of the out-of-band radiation of the radio signal of the radio transmitter P _m and transmits this data to the first input of the block for calculating the parameters of the baseband filter 11.2.

Information about the parameters of protected priority signals (amplitude-frequency (spectral) characteristics, data on the rating of the radio frequency carrier, type and parameters of modulation / manipulation, value the minimum allowable ratio of the power of the protected radio signal to the power of the interfering radio signal Q _d ).

The data block on the parameters of the protected radio signals 11.1 transmits data on the characteristics of the protected priority radio signals to the radio receiver 11.4, and the value of the allowable ratio Q _d transmits to the second input of the block for calculating the parameters of the baseband filter 11.2.

The radio receiver 11.4, having received information from the block for determining the parameters of the radio signal 11.3 and from the data block about the parameters of the protected radio signals 11.1, provided that the value of the carrier frequency of the protected signal falls into the frequency band of the out-of-band radiation of the radio signal of the radio transmitter, tunes to receive the protected priority radio signal.

On the time interval of operation of the radio transmitter with automatic adjustment of the parameters of the spectrum of the radio signal, the radio receiver 11.4, according to the established time schedule, receives the protected priority radio signals 13 and/or 14 and transmits information about the absence or presence of the protected radio signal 13 and/or 14 with an estimate of its power P _h to the third input of the block for calculating the parameters of the baseband filter 11.2.

The block for calculating the parameters of the base band filter 11.2, having received information from the radio receiver 11.4, fixes the fact of detection or non-detection of the protected radio signal 13 and/or 14 in the frequency band of the out-of-band radiation of the radio signal of the radio transmitter and controls the operation of the base band filter 3 in accordance with the following algorithm.

1) If the protected radio signal 13 and/or 14 is not detected in the current time interval, then the base band filter parameter calculation unit 11.2 generates and transmits to the base band filter 3 a command to turn off the filter, which corresponds to the absence of filtering of the spread spectrum information signal x in the filter base band 3 (Fig. 2), and the switch 5 transmits a codegram with a command to enable the broadcast of the BPSK signal from the output of the modulator 4 to the input of the amplifier 6.

2) When a protected radio signal 13 and/or 14 is detected within the sidelobe bands of the BPSK spectrum of the radio transmitter signal, the baseband filter parameter calculation unit 11.2 performs:

- calculation of the current ratio of the power of the protected radio signal P _c to the power of the out-of-band radiation of the radio signal of the radio transmitter P _m within the operating frequency band of the protected radio signal

Q _t \u003d P _s / P _m ;

- comparing the calculated value Q _t with the allowable value of the ratio of the power of the protected radio signal to the power of the interfering radio signal Q _d and making a decision to fix the fact of the critical negative impact of the interfering radio signal on the reception of the protected radio signal 13 and/or 14 in accordance with the following logic:

a) if Q _d ≤ Q _t , then the fact of the critical influence of the out-of-band radiation of the radio signal of the radio transmitter on the reception of the protected priority radio signal is not fixed, and the base band filter parameter calculation unit 11.1 sends a command to turn off the filter to the base band filter 3, which corresponds to the absence of information signal filtering spread spectrum x in the baseband filter 3 (Fig. 2), and to the switcher 5 transmits a codegram with a command to allow the broadcast of the BPSK signal from the output of the modulator 4 to the input of the amplifier 6;

b) if Q _d > Q _t , then the fact of the critical influence of the interfering radio signal on the reception of the protected priority radio signal is recorded, after which the base band filter parameter calculation unit 11.1 generates and transmits to the base band filter 3 the command to turn on the filter and the value of the rounding coefficient of the filter frequency response α ≈1, which corresponds to the filtering of the side lobes of the spectrum of the information signal of the spread spectrum x in the base band filter 3 to a level of -50 dB relative to the level of the base band of the spectrum (Fig. 4), and the switch 5 transmits a codegram with a command to allow the broadcast of a BPSK signal from the output of the modulator 4 to the input of amplifier 6.

3) When a protected radio signal 13 and/or 14 is detected within the redundancy bands of the main beam of the BPSK spectrum of the radio transmitter signal, the calculation unit for the base band filter parameters 11.2 performs:

- calculation of the current ratio of the power of the protected radio signal P _c to the power of the out-of-band radiation of the radio signal of the radio transmitter P _m within the operating frequency band of the protected radio signal

Q _t \u003d P _s / P _m ;

- comparing the calculated value Q _t with the allowable value of the ratio of the power of the protected radio signal to the power of the interfering radio signal Q _d and making a decision to fix the fact of the critical negative impact of the interfering radio signal on the reception of the protected radio signal 13 and/or 14 in accordance with the following logic:

a) if Q _d ≤ Q _t , then the fact of the critical influence of the out-of-band radiation of the radio signal of the radio transmitter on the reception of the protected priority radio signal is not fixed, and the base band filter parameter calculation unit 11.1 sends a command to turn off the filter to the base band filter 3, which corresponds to the absence of information signal filtering spread spectrum x in the baseband filter 3 (Fig. 2), and to the switcher 5 transmits a codegram with a command to allow the broadcast of the BPSK signal from the output of the modulator 4 to the input of the amplifier 6;

b) if Q _d > Q _t , then the fact of the critical influence of the interfering radio signal on the reception of the protected priority radio signal is fixed, after which an iterative procedure for calculating the parameters of the base band filter is performed.

The step-by-step implementation of the procedure for calculating the baseband filter parameter is as follows.

Step 1. Initial values of quantities: i=1; α ₁ =1; α ₀ =0; ΔQ is a finite positive value that determines the accuracy of determining the value of the rounding coefficient of the frequency response of the filter α _i and the convergence of the iterative procedure.

Step 2. Setting the number of the next iteration i=i + 1.

Step 3. Determining the value of the rounding factor of the filter frequency response α _i :

α _i = α _i-1 - | α _i-1 - α _i-2 | / 2 if Q _d > Q _{t i-1} ;

α _i = α _i-1 + | α _i-1 - α _i-2 | / 2 if Q _d ≤ Q _{t i-1} - ΔQ.

Step 4. Transferring the results of calculating the value of the rounding coefficient of the frequency response of the filter α _i to the input of the baseband filter 3 and restructuring the filter.

сужается (на фиг. 6 показан спектр BPSK сигнала, обработанного в фильтре основной полосы 3 с параметром α≈0, при котором

).Step 5. Filtering the information signal of the spread spectrum x in the tuned baseband filter with the rounding factor of the filter frequency response _αi, resulting in the redundancy band of the BPSK spectrum processing of the signal of the radio transmitter

narrows (Fig. 6 shows the spectrum of the BPSK signal processed in the baseband filter 3 with the parameter α≈0, at which

).

Step 6. Determination of the current value of Q _{t i} and control of the ratio of Q _d and Q _{t i} :

- if |Q _d -Q _{t i} | > ΔQ - go to step 2;

- otherwise, the filter tuning stops and a codegram is transmitted to the switch 5 with a command to enable the broadcast of the BPSK signal from the output of the modulator 4 to the input of the amplifier 6.

The switch 5, having received from the block for calculating the parameters of the base band filter 11.2, the codegram with the command to enable the broadcast of the BPSK signal, switches and broadcasts the BPSK signal from the output of the modulator 4 to the amplifier 6.

Amplifier 6 amplifies the BPSK signal and passes it to the bandpass filter 7, which provides attenuation of harmonics and combinational components of the spectrum of the amplified BPSK signal and transmits this signal to the antenna-feeder device 8.

Antenna-feeder device 8 converts the amplified BPSK signal into a radio signal and radiates it into space.

Thus, if the protected radio signal is not detected during the monitoring of the electromagnetic environment, or the fact of the critical negative effect of the interfering radio signal of the radio transmitter on the reception of the protected radio signal is not detected, the spread spectrum information signal x is not filtered in the base band filter of the BPSK signal. In this case, the level of out-of-band radiation of the radio transmitter will be significant and will be minus 10-13 dB relative to the radiation level of the main band, the width of the redundancy bands of the main lobe of the spectrum will be 1/2T _c , where T _c is the repetition period of the SRP of the spread spectrum signal (Fig. 2 shows example of the spectrum for T _c = 1 μs), and the energy efficiency of the radio transmitter will be maximum (the value of the crest factor of the generated BPSK signal is 3 dB, see Fig. 3).

If, when monitoring the electromagnetic environment, the fact of a critical negative effect of the interfering radio signal of the radio transmitter on the reception of the protected radio signal emitted within the bands of the side lobes of the BPSK signal spectrum is fixed, then the information signal of the spread spectrum x will be filtered in the filter of the base band of the BPSK signal with the value of the rounding coefficient of the filter frequency response α≈1. In this case, the level of the side lobes of the spectrum of the information signal of the spread spectrum x in the base band filter 3 is reduced to minus 50 dB relative to the level of the base band of the spectrum, but the width of the redundancy bands of the main lobe of the spectrum will remain equal to 1/2T _c (see Fig. 4). The energy efficiency of the radio transmitter in this case will decrease (the crest factor will increase to 4.75 dB, see Fig. 5) as a payment for providing the EMC of the radio transmitter with priority radios operating in the radio frequency bands of its out-of-band radiation.

If, when monitoring the electromagnetic environment, the fact of a critical negative effect of the interfering radio signal of the radio transmitter on the reception of the protected radio signal emitted within the redundancy bands of the main lobe of the BPSK signal spectrum is fixed, then adaptive filtering of the information signal of the spread spectrum x in the filter of the base band of the BPSK signal will be carried out depending on the ratio the power of the protected radio signal to the power of the out-of-band radiation of the radio signal of the radio transmitter. In this case, the average level of the signal spectrum within the out-of-band emission bands of the BPSK signal spectrum of the radio transmitter will remain at a level of minus 50 dB relative to the base band level (see Fig. 5), and the width of the redundancy bands of the main lobe of the BPSK signal spectrum will adaptively decrease and in the limit case at α≈0 will be equal to zero (see Fig. 5). However, in this case, the energy efficiency of the radio transmitter is adaptively reduced (the crest factor value is increased to 7 dB), as a payment for providing EMC of the radio transmitter with priority radio facilities operating in the radio frequency bands of its out-of-band radiation.

Thus, the proposed technical solution provides an increase in the efficiency of using the energy resource of the radio transmitter by adaptive dynamic control of the parameters of the spectrum of the emitted BPSK radio signal, depending on the results of monitoring the electromagnetic environment in the radio frequency bands of the out-of-band radiation of the radio transmitter.
