信道主要模拟信号的多径传输，在这个信道中一共有三个用户的数据进行传输，用户一经过了2径衰落，用户二经过了3径衰落，用户三经过了4径衰落。(The main channel simulation of multipath signal transmission, in this channel has a total of three users of the data transmission, the user after 2 path fading, the user of two after 3 path fading, the user of three after 4 path fading. )

covolution is a technique used to sample two signals producing the third signal.there are two types of convolution namely linear and circular convolution.

一个mimo系统的程序，其中包括注水定理的函数。(A mimo system procedures, including injection function theorem.)

该代码是mimo仿真源代码对学习mimo入门很有帮助(The source code is emulation mimo mimo entry helpful for learning)

精通matlab程序，包括遗传算法以及粒子群优化算法程序(Proficient in matlab procedures, including genetic algorithm and particle swarm optimization algorithm program)

基于基本LMS的自适应噪声抵消程序,对一音频信号去噪,效果不错(based on the basic LMS adaptive noise cancellation procedures, an audio signal denoising good results)

该代码基于灰色GM(1,1)算法，使用时，需要在函数中将自变量取为时间序列，可预测任意时间的数值(The code is based on gray GM (1,1) algorithm, when used in the function argument will be taken as time series, can predict the value of any time)

this file contains many programs of wavelet algorithm
