一束光通过一个透明圆柱体，圆柱后有一个屏幕，程序最终反映屏幕上的 图象随圆柱半径的变化而变化。其中光强分布是采用相干叠加原理，因为其中采 样点数目不足，所以光强分布的结果和真实的有一定差距。增加采样点数目和改 变采样点范围能够改善输出光强的结果逼真程度。(一束光through a transparent cylinder, a cylindrical post-screen process will ultimately reflect the on-screen image with the cylindrical radius change. Light intensity distribution of which is the principle of coherent superposition, because the insufficient number of sampling points, so light intensity distribution of the results and have some real gaps. Increase in the number of sampling points and to change the scope of sampling points can improve the outcome of the output light intensity the degree of realism.)

模拟整个扩频系统，为学习和设计有关扩频系统提供帮助，里面有信号的发生和接受端信号的捕获，文件夹里面的m文件可直接在matlab上实现(Simulate the spread spectrum system for the study and design of spread spectrum systems to help, there are signal generation and signal capture the receiving end, inside the folder in the matlab m files can be directly implemented on)

matlab关于灯光显示效果与背面灯光效果的程序(Matlab on the lighting effects, lighting effects and the reverse procedure)

这是贪婪算法的主程序以及它所调用的子程序。(This is the main program of the greedy algorithm and the subroutine it calls.)

根据接收数据阵x 、信道长度LH、过采样因子q ，采用Hopfield 盲处理方法，恢复出相应于x的尽可能长的BPSK发送序列，并估计 信道。(Based on the received data matrix x, the channel length of the LH, oversampling factor q, with Hopfield blind treatment, recovery corresponding to x, send a sequence of BPSK as long as possible, and the channel estimate.)

本段matlab程序主要是娱乐性质的，功能是用这些代码运行后会有演奏卡农的效果，非常的神奇，时候MATLAB高手研究。(This paragraph matlab program of entertainment nature, functions will be played after the code is running Canon is very magical, when MATLAB master research.)

纯语音和带噪语音,信噪比,带噪语音的产生,语音信号的预处理一——消除趋势项和直流分量(Pretreatment with a pure voice and noisy speech signal to noise ratio, resulting in noisy speech, the speech signal- to eliminate the trend term and DC components)
