Background technology
Cellular system is also " Small Section Mode " system.It is that the distribution density of the radius visual user of each community is at about 1 ~ 10km for several communities by all regional classifications to cover.It it is the user's service in this cell range in one base station of each Cell Setup.And power system capacity can be improved further by cell splitting.
This system is made up of the transmission line of mobile services switching centre (MSC), base station (BS) equipment and mobile platform (MS) (subscriber equipment) and switching centre to base station.This class is broadly fallen at present in 900MHz first generation mobile communication system (TACS) analog systems of China's operation and second generation mobile communication system (GSM) digital display circuit.
That is the mobile switching centre of mobile platform and public switched telephone network (be exactly we at ordinary times described in telephone network PSTN) between be connected, mobile switching centre is responsible for connecting the communication between base station, in communication process, mobile platform (such as mobile phone) is set up with own base station and is contacted, it is connected with mobile switching centre again by base station, is finally linked into public telephone network.
Honeycomb fashion public land mobile system is applicable to fully automatic selection, full duplex work, Large Copacity Public Mobile Land net networking, can be connected by primary centre any with public telephone network, it is achieved the talking connection of mobile subscriber and local call network users, long-distance call network users and overseas call network users.This system has the functions such as handover, automatic or manual roaming, charging and traffic volume measurement
Such as in Chinese patent literature CN1264996A, disclose the preprocess method of a kind of processing wireless measured data in cellular mobile communication system.But, in technical scheme disclosed in this patent documentation, if signal distortion or weaken in transmittance process, detection for wireless data will disappear in transmitting procedure, with regard to sample, it is therefore necessary in wireless data signal transmittance process, signal is carried out pretreatment.
Summary of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of transmission path, method that wireless data carries out pretreatment by narrow pulse signal that what loss was little adopt.
For solving above-mentioned technical problem, the technical solution used in the present invention is, the method that wireless data is carried out pretreatment by this employing narrow pulse signal, it is characterised in that comprise the following steps:
(1) gather the wireless data in cell mobile communication systems, and wireless data is carried out Preliminary detection；
(2) Preliminary detection in described step (1), elimination period of waves, the fluctuation less than signal period N formed filtering signal；
(3) filtering signal in described step (2) is inputted to SRD Gauss narrow pulse generating circuit formation narrow pulse signal, more described narrow pulse signal is exported subnanosecond level, second-order differential Gaussian pulse signal through second-order differential Gaussian particle filter circuit；
(3) adopt calculation element that output subnanosecond level, second-order differential Gaussian pulse signal in described step (2) are calculated, calculate transmission characteristic according to the picture signal characteristics of feedback；
(4) according to the picture signal characteristics of feedback in step (3), step (2) and (3) is repeated；
(5) signal is exported.
In technique scheme, wireless data signal is transformed into narrow pulse signal, and then convert subnanosecond level, second-order differential Gaussian pulse signal to, the problem avoiding or even eliminating distorted signals, signal is less by external interference factor, simultaneously, in this application, for enhancing signal, signal transfer characteristic is calculated, and feed back wireless data signal feature, signal characteristic according to feedback, repeats step (2) and (3), improves wireless data signal quality, efficiency is high and cost is low, and loss is little.
Further it is improved by, in described step (1), after gathering the wireless data in cell mobile communication systems, receives suspect signal, conversion is applied to described reference signal to provide the set of the position after converting；And use the discrete sampling locations in the adjacent domain around point spread function position after described conversion that the phase place of described suspect signal is sampled, and provide described suspect signal with described conversion after the estimated value of phase place at position corresponding place.
