中文说明：基于互功率谱的时延估计，用于信号特征提取、信号消噪，仿真效果非常好，欢迎大家下载学习，利用matlab GUI实现的串口编程例子，考虑雨衰 阴影 和多径影响。
English Description：
Based on the cross power spectrum time delay estimation for signal feature extraction, signal denoising, simulation results is very good, welcome everyone to download to learn, using Matlab GUI to realize the serial programming examples, consider rain fading shadowing and multipath effects.
