this program implement the dwt discret tranform wavelet

LDPC编码的matlab实现，好用，利于初学者。(LDPC coding matlab implementation, easy to use, help for beginners.)

从已经出现故障的信号中，提取能够反映该信号故障特征的值，以后就能根据数值直接判断别的信号有没有出现该故障，更加直观(Signals the fault has appeared in the fault feature extraction and can reflect the value of signal, after can according to numerical directly to judge the other signals have appeared the fault, more intuitive)

本文介绍了如何利用excel link实现Excel与Matlab混合编程。通过连接Excel和Matlab，用户可以在Excel工作表空间和宏编程工具中使用Matlab的数值计算，图形处理等功能，不需要脱离Excel环境。(This article describes how to use excel link Excel and Matlab achieve. By connecting Excel and Matlab, Matlab users can use the numerical calculations, graphics and other functions in an Excel worksheet and macro programming tool space, without departing from the Excel environment.)

在MATLAB仿真环境下，该程序是对OFDM系统的发送端的模拟仿真实现(In the MATLAB simulation environment, the program is the sending end of the OFDM system simulation experiment)

分析了该信号的时域、频域、倒谱，循环谱等,包含CV、CA、Single、当前、恒转弯速率、转弯模型，考虑雨衰 阴影 和多径影响，能量熵的计算，用于特征降维，特征融合，相关分析等,是国外的成品模型。( Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. It contains CV, CA, Single, current, constant turn rate, turning model, Consider shadow rain attenuation and multipath effects Energy entropy calculation, For feature reduction, feature fusion, correlation analysis, Foreign model is finished.)

This code takes speech as input, removes silence region based on zero crossing rate and energy.output of the code is only voiced region of the input speech signal.the input is of the .wav format.
