THIS is a matlab code of sppech compression

butterworth filter for image processing

fuzzy c means clustering

colea程序，处理语音信号的M函数集合，对于学习语音处理有很大帮助(colea procedures to deal with M-function voice signal a collection of voice processing for the study of great help)

uploaded the polar codes for cooperative relay networks and the same can be used for compression

calculates a very simple version 1D of a zone plate

说明：  该课题为基于kmeans的聚类分割，输入一张彩色图像，可以选择需要分割成多少类，就会以不同颜色区分不同的块，带有GUI界面，操作丰富。(This topic is based on Clustering Segmentation of kmeans. Input a color image, you can choose how many categories you need to segment, and then different blocks will be distinguished with different colors, with GUI interface and rich operation.)

Windowed mutual information

压缩包里有OFDM信号的分析，频谱，星座图，加窗(Compression bag with OFDM signal analysis, spectrum, constellation, plus window)

说明：  文档中有3个程序。h.264灰度处理程序，DCT变换程序，DCT系数量化程序。(There are three programs in the document. The h.264 gray handler, and DCT transform process, the DCT coefficient quantization process.)
