对相移键控信号调制解调原理进行了分析,并对未知信号的载波频率和码速率估计方法进行了分析与比较,推导出了相移键控和振幅相移联合键控信号盲解调的公式,并结合4PSK,8PSK,16PSK和16QAM信号进行盲解调仿真,在不同信噪比下对不同类型的相移键控信号盲解调正确解调波特率的影响进行了分析,并给出了分析结果,给通信对抗侦察提供了理论指导.%The analysis is fulfilled about principle of PSK signal. And comparison of carrier wave frequency and code velocity estimation method is jmpleted. Formula of PSK remodulation is deduced. The simulation and analysis of4PSK, 8PSK, 16PSK and 16QAM blindness remodulation are fin hed. The result of right remodulation probability at the relevant signal noise rate is educed by computer simulation. A direction reconnaissance of com unication electronic warfare is given.
