harris的matlab程序，精度不是很高，但是大家可以根据需要进行改写(harris)

这是用matlab开发hmm模型，里面包含全部的有关hmm的程序，都可以使用，对于hmm的初学者来说，是极好的的学习程序。(HMM)

matlab程序将传递函数通过Z变换使其离散化，然后再把得到的脉冲传递函数改写成差分方程。便于接下来一步的C程序编程。(matlab program will transfer function Z-transform them through discrete, then put the resulting pulse transfer function of a differential equation rewritten. Facilitate the next step of the C programming.)

此文件包含着EEMD的能量特征分量的计算程序和EEMD之后进行各个IMF的KL散度指的计算程序。(This file contains the energy characteristic component EEMD computational procedures and after each EEMD KL divergence refers to the IMF s calculation program.)

QPSK modulation and again demodulation

三分之一倍频程表示的短时傅里叶变换，需要时域分析工具箱(One-third octave express the short-time Fourier transform, the need for time-domain analysis toolbox)

小波变换相关方法的MATLAB实现，可以在同地幅图像中显示四幅不同的波段，包括三个高频和一个低频。(MATLAB Wavelet Transform Correlation method implemented in the same way images can be displayed in four different bands, including three high and one low-frequency.)

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )
