this is very good book, so i want to upload this here

采用matlab编程的DTMF检测程序仿真，经过测试，绝对可用，可检测多个DTMF信号！(using Matlab programming DTMF detection process simulation, tested and absolutely can be used, can detect DTMF signals over!)

本程序实现了语音信号中的信息隐藏，采用DCT和LSB方法。(the information hiding technique is completed with the carrier of voice signal.)

高斯混合模型对目标说话人识别的matlab源程序(Gaussian mixture model of the target speaker recognition matlab source)

source code in matlab for binarization some text

PN Codes Correlation Properties

function g=nonlineareq(x) Here is an example of nonlinear system that can be solved by using the Matlab command "fsolve" written in the file called "solution.m"

suppression of echo by using lms code

有限干扰下的单向中继选择；基于多种选择策略 有篇比较好的paper 还有就是仿真的程序 test4是最后两个图的 有点小问题 (Limited interference unidirectional relay selection strategy papers based on multiple choice paper there is a better simulation program test4 last two graphs is a little problem)

小波变换的MATLAB变换程序 可以对信号进行降噪声处理(xiaobobianhuan.m)
