说明：  本程序是Haar小波的源代码，非常使用。(This program is the source code for Haar wavelet, is used.)

特征提取是模式识别中最重要的一个部分，这里提供的matlab代码计算一些基本的话音特征，而且，提供了一个简单的基于直方图的特征分类方法的实现。基本的特征包括：特征统计、Energy Entropy Standard Deviation (std)、均值信息熵、过零率检测、频谱衰减等等六个特征(Pattern recognition feature extraction is the most important part, here' s matlab code to compute some basic voice features, but also provides a simple classification method based on histogram characteristics of the implementation. Basic features include: Features and Statistics, Energy Entropy Standard Deviation (std), mean entropy, the zero-rate detection, attenuation, and so the six characteristics of the spectrum)

极坐标，对数极坐标变换及其反变换分类:matlab与图像处理(polar coordinates, very few of coordinate transformation and its inverse transform Categories : MATLAB and Image Processing)

一个基于Music算法的DOA估计程序，该程序为Matlab的图形用户界面的形式，方便各种参量的仿真！(A estimation program of DOA based on Music aigorithm. It is convenient to simulate many situation!)

Hidden_Markov_model_for_automatic_speech_recognition This code implements in C++ a basic left-right hidden Markov model and corresponding Baum-Welch (ML) training algorithm. It is meant as an example of the HMM algorithms described by L.Rabiner (1) and others. Serious students are directed to the sources listed below for a theoretical description of the algorithm. KF Lee (2) offers an especially good tutorial of how to build a speech recognition system using hidden Markov models.

混合高斯em算法 very good for chinese

Code to simulate QAM modulation and demodulation. Also has an AWGN function to add noise to symbols. A Rayleigh and Rice process are added as a part to simulate a complete communication system and uate its behavior.
