BER性能分析。参数开放，宜用。多给意见。(BER performance analysis. Parameters of open and suitable. Give advice.)

An Improvement to JPEG Compression

说明：  节点导纳 Matlab程序,调用数据文件即可(Node admittance Matlab program, call the data file can be)

这是用itpp库编写的卷积码的解码程序。由于用C++库和Intel的MKL库，所以速度飞快。同样的仿真点数， Matlab2012下用了15分半钟，而这个程序仿真只用了半分钟，相当于是matlab速度的30多倍。(This is itpp prepared for the convolutional code decoding process. Because with C++ libraries and Intel' s MKL library, so fast. The same simulation points under Matlab2012 spent 15 and a half minutes, and this program simulation with only half a minute, the equivalent of 30 times the speed of matlab.)

对采集到的振动信号进行EMD分解，得到一系列频率不同的经验模态函数IMF分量，可以用来滤波和提取原信号的特征。(The collected vibration signals of EMD, get a series of different frequency components of IMF empirical mode function can be used to filter and extract features of the original signal.)

图像处理之中的对已经预滤波的信号进行多小波分解的Matlab实验程序(Image processing are already pre-filtering of the signal decomposition Matlab Multiwavelet experimental procedures)

很经典的蚁群算法的matlab源码，也可以用c++实现，不过要复杂很多，用matlab比较简单。(classic ant colony algorithm source Matlab can also use the c achieve, but many complex, Matlab using relatively simple.)
