| 摘 要： | 本文说明了ＢＰＳＫ信号的小波变换呈现出较好的相关性，利用这点可以实现对低信噪比的ＢＰＳＫ信号进行检测和参数提取．对直扩信号侦测的计算机模拟结果表明，该方法不仅能检测到低信噪比的此类信号，而且能提取到扩频码周期等参数。在多信号情形下还可利用ＢＰＳＫ信号的小波相关性对信号进行分离。

| Abstract: | In this paper we introduce the conception of wavelet correlation, which existing in the BPSK signal clearly, and two applications in the detection of BPSK signal. One is the detection of low SNR DSSS signal and extraction of length of PN code, the other is detection of BPSK signal from multi signals. |
