The Matlab NLMS algorithm

用matlab写的模糊RBF辨识程序，做成了一个函数。(it is very important.)

小数据量计算利亚普诺夫指数(Liapunov index of small amount of data calculation)

最大相关熵准则自适应滤波，凸组合，两个滤波器(mcc filtering, convex combination, two filters)

说明：  该代码可以仿真直接扩频系统不同正弦幅度下误码率的的大小(Simulation of bit error rate of direct spread spectrum system)
