摘要
研究了扩频信号的周期平稳性及其循环谱密度函数;在推导出BPSK扩频信号的循环谱密度函数的基础上,提出利用循环谱理论对BPSK直扩信号进行检测,并用MATLAB进行仿真验证。
This paper mainly studies the cycle placidity and cycllic spectrum density function of DS signal:On the base of cyclic spectrum density function of BPSK DS signal,,the writer puts forword a theory that makes use of the cyclic spectrum to detect DS signal,with the simulation ways of MATLAB to validate it.
