| 摘 要： | 详细介绍了小波变换模极大值去噪的原理,以BPSK信号为例研究了自相关检测方法。最后对基于小波变换的直扩信号的检测系统用Matlab软件进行了仿真,验证了该方法的可行性。证明该方法明显优于传统的直接对接收到的直扩信号进行检测的方法。

| Abstract: | This thesis has introduced in detail the principles of wavelet transform modulus maxima de-noising method and studied the auto-correlation detection method of the DSSS signal,taking the BPSK signal as an example.Finally,simulation is given in this paper,using Matlab to validate the research on detecting direct spread signal based on wavelet transform method.This method is better than the traditional methods that detect the signal directly. |
