摘　　要：根据韦瓦(W eawa)单边带调制解调法、COSTAS锁相环及双线性变换,提出基于软件无线电的单边带锁相解调器。解调器运行在TMS320C6203上,能实时处理160kHz信号,捕捉8kHz频偏。The SSB modulation technique has many advantages of narrow band, high SNR, low emission power, however the demodulation is complex, According to Weawa method, COSTAS-PLL, dual linear transform, a new SSB PLL demodulator based on SDR is brought out. The demodulator which runs on TMS320C6203 is capable to process real-time 160kHz signal and capture 8kHz frequency deviation.
