说明：  经验模态分解（Empirical Mode Decomposition，简称EMD))方法被认为是2000年来以傅立叶变换为基础的线性和稳态频谱分析的一个重大突破，该方法是依据数据自身的时间尺度特征来进行信号分解，无须预先设定任何基函数。这一点与建立在先验性的谐波基函数和小波基函数上的傅里叶分解与小波分解方法具有本质性的差别。(Empirical mode decomposition (EMD) method is considered as a major breakthrough in linear and steady-state spectrum analysis based on Fourier transform since 2000. This method decomposes signals according to the time scale characteristics of the data itself, without setting any basis function in advance. This is essentially different from Fourier decomposition and wavelet decomposition based on prior harmonic basis function and wavelet basis function.)

信号空间分集ssd的误码率分析，m语言实现，最大似然译码。(Ssd signal space diversity analysis of bit error rate, m language, maximum-likelihood decoding.)

Statistical Analyses Examples

计算瑞雷波频散曲线GUI小程序，matlab写，内含使用说明(Rayleigh wave dispersion curves calculated GUI applet, matlab write, containing instructions for use)

利用小波变换算法对灰度图像进行压缩,效果比较好( Carries on the compression using the wavelet transformation algorithm to the gradation image，and the effect is good. )

Matlab实现的带通滤波器(Matlab the band-pass filter)

The code introduces postcoding technique in ofdm system that results in a much less complex mechanism and provide similar result as are obtained with precoded system. In this technique the coding part is done after the ifft block that is initially the data is converted to frequency domain n then coding is introduced.

说明：  在MATLAB平台上通过实验进一步了解离散小波变换，加深对小波变换的理解(Digital watermarking based on Wavelet Transform)
