两个重要文件：

1、Rayleigh_Doppler_singlePath.m

产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法；

2、Rayleigh_Doppler_multiPath.m

根据多条径的延时和强度，产生频率选择性衰落；



在单径和多径两个程序中，均提供了其功率谱的输出代码； -Two important documents: 1, Rayleigh_Doppler_singlePath.m to generate a single path Rayleigh fading, using six kinds of ways and compared, 6 recommended methods　2, Rayleigh_Doppler_multiPath.m under a number of path delay and intensity, resulting in frequency selective fading　in both single path and multi-path process, provide the output of its power spectrum code
