fast smoothing of noise images

图像尺度为2的全分解小波包，Harr小波变换，一个主程序，两个附程序。(2 full-scale image wavelet packet decomposition, Harr wavelet transform, a main program, two additional programs.)

计算香浓熵，用于信号处理，表征信号混乱度。试过了，可以正常使用(Shannon entropy is calculated for signal processing and signal confusion is calculated. Tried, can be used normally)

LDPC码是目前通信中性能最好的纠错编码之上，这是我在Matlab下编写的LDPC基本解码算法，已经通过调试，大家共同学习(LDPC code is the best communication performance on error-correcting code, this is my prepared in Matlab basic LDPC decoding algorithm has been through debugging, U.S. co-learning)

说明：  可以进行滤波处理的matlab程序 保证可以使用 (Can deal with the matlab filtering procedures to ensure that you can use)

说明：  ppt for project development

The C++ Programming Language(Bjarne Stroustrup著) 书中第五部分附录及代码(The C++ Programming Language Calculation Codes)

This code generate LFM chirp with any length, cycles, delays, and phase offsets. It also ensure continous phase change from one pulse to the other.

实现近似熵算法。可以根据需要对程序进行必要地修改。(Achieve approximate entropy algorithm. Can carry out the necessary procedures needed to modify.)
