| As wireless communications technology development,People according to the communications functions and communications requirements of the different,has drawn up very many correspondence patterns,used for to meet people's various needs. To implementation in different situations can best and most economical way communication ,support multiple communication mode closed will be the future development of inevitable. Radio of the software brought us new theory mode,through the software platforms run different software modules,to adapt many kinds of signal modulation waveform and transport protocols,maximum meet participate needs of the interconnected.Synchronization is communication system inseparable part of the, directly affect received signal realization with quality. In multi-pattern communications system especially important,synchronization is communication system carries on the intelligence transmission the premise,c he different system is different to the synchronized request, and solutions different, Inevitably based on the wireless software apattern of communication platform synchronizing data processing capability sets higher demands. This paper established a suitable for the full digital BPSK of receiving extraction synchronization carrier method: COSTAS locked in france. Further analyzed COSTAS road works,to the main the module made details and design,and MATLAB of the algorithm a simulation, the simulation result indicated that this kind of position synchronization algorithm simplified the demodulation process,r educe the computational,the resistance to interference is better than the traditional position synchronization method. Conclusions for actual synchronization scheme design,h as the important guiding sense. |
