说明：  使用MATLAB实现（7，4）循环码的编译码(Use MATLAB to achieve (7,4) coding and decoding of cyclic codes)

采用LS 和MMSE算法对OFDM系统进行信道估计,很不错的含有详细的解析呢(using LS and MMSE algorithm OFDM system channel estimation, a good way of containing detailed analysis?)

this matlab code to help you finding the Color Image Threshold

基于GMM的话者识别matlab程序，训练运行train.m,识别运行recog.m(speaker identification system based on GMM)

Adaptive filtering algorithm based on LMS (B-LMS), to fast track the process of change in channel between transmitter & receiver

《自适应滤波器》第五章Chap_5_Pred源代码，很详细(" Adaptive Filter" Chapter V Chap_5_Pred source code, very detailed)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)

数字信号解调（接收端），包括：“删除干扰噪声信号”，“从载波信号中提取原始信号”，“滤波器滤波”，“用PSK解码，把图形变成数字信号”。(Digital signal demodulator (receiver), including: " to remove interference noise signal," " carrier signal extracted from the original signal," " filter" , " with PSK decoding, graphics put into a digital signal." )

模极大值滤波，对信号进行分解和重构。所采用信号是matlab自带信号。(Modulus maxima filtering, the signal decomposition and reconstruction. Signal is used in signal matlab own.)
