nmls to solve stochastic problems

基于lms的自适应滤波器仿真设计,已测试可用(Simulation design of adaptive filter based on LMS)

webrtcd的aec模块的matlab实现，包括了频域NMLS滤波以及后期的非线性处理部分。可以得到较好的回声消除效果。(Matlab implementation of AEC module of webrtcd includes frequency domain NMLS filtering and later non-linear processing. A better echo cancellation effect can be obtained.)
