MU-OFDM_release

The sourcecode is about optical character recognision using matlab.

最大似然（ML）准则和最大后验概率（MAP）准则Matlab仿真(Maximum Likelihood (ML) criteria and maximum a posteriori probability (MAP) criteria Matlab simulation )

频带方差端点检测的matlab源程序，可以看看，觉得还可以。(Band variance of endpoint detection matlab source code, you can see that also.)

使用Matlab去LOCATE语音信号，尤其是UNVOICED的语音信号(how to locate the beginning and end of the speech, especially when the signal start from the unvoiced character)

多元曲线解析-交替最小二乘法,MCR-ALS(Multivariate Curve Analysis- alternating least squares method, MCR- ALS)

这是与之前上传的Extract_test_IMFCC里面的一个子函数，pudn程序不能一次上载几个函数，只好分开(This is one subfunction of Extract_test_IMFCC uploaded before.Since pudn.com cannot upload several functions, they must divided.)

对matlab中的常用函数进行补充，对信号处理的实现有帮助，只要将其加入默认路径就能轻松使用。(the commonly used matlab functions added that implementation of signal processing has to help, as long as its default path will be able to add easy to use.)

说明：  包括直接序列扩频CDMA的调制和解调函数(Including direct sequence spread spectrum CDMA modulation and demodulation function)

CHORDSOL Chord method code for scalar equations. This code terminates on small relative-absolute errors, function [X, HIST] = CHORDSOL(X, F, TOLA, TOLR) Inputs: X = initial iterate F = function TOLA = absolute error tolerance TOLR = relative error tolerance Output: x=approximate result

solved program QAP using ICA
