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 )

UseCImplementOOP
如何用C实现OOP的特性，有趣吧。这本英文书给出细节，对于深入理解C和OOP的特性区别非常有帮助。当然读者必须有比较深的编程经验，初学者或一般程度者慎入！(How to OOP with C to achieve the characteristics of interesting. This book gives details of the English, for in-depth understanding of the characteristics of differences between C and OOP very helpful. Of course, the reader must have a relatively deep programming experience, beginners or general level by Shen Ru!)
