摘要
基于周期平稳信号特征和频谱相关密度，本文提出了利用频谱相关处理检测扩频通信信号的频谱相关检测方法。这种方法的检测性能优于常规经典方法，并有更好的抗噪声和干扰的能力。
Based on the characterities of a cyclostationary random signals and spectral correlation density,a detected method of spectral correlation for SS communications is proposed using spectral correlation processing in this paper This method could detecte the signals of SS communications and estimate the signal paraments with better properties than conventional classics method in noise and interference environments
