说明：  LTE系统中QPSK软信息解调,Turbo编码matlab仿真程序，(soft QPSK demodulation in LTE )

说明：  利用小波包变换对一个二维含噪图像进行分析处理。(using wavelet transform packets of a two-dimensional images with noise analysis.)

考虑不同频率复用因子的情况下用户的容量和SINR值变化情况，得出在FRF为3的情况下达到最大的值(calculate the edge user under different frequence reuse factor the performance of capacity and SINR. The result is that when FRF equals to 3 achieve the maximum value.)

粒子群优化的kriging近似建模程序包DACE-PSO，matlab程序，比传统的dace程序设置更少的参数(PSO kriging approximation modeling package DACE-PSO, matlab program package than traditional dace advantage: without determining Sigma parametersdetermine the Sigma parameters)

Matlab快速傅立叶变换程序，有源代码。(Matlab Fast Fourier Transform program, active code.)

In this program we demonstrate the MP, OMP, WMP, and Thresh algorithm, by running them on a set of test signals and checking wether they provide the desired outcome

利用MATLAB编写的关于频谱细化(Zfft)的程序,有注释。(Spectrum zoom (Zfft) program using MATLAB There are notes in it. )

由于Kmeans聚类分析是一个局部的搜索过程，因此加入遗传算法进行全局搜索选择最优的初始中心点使得Kmeans算法产生较大的改进(Since Kmeans Cluster analysis is a local search process, so join a global search for the genetic algorithm to the optimal initial centers such Kmeans algorithm produces greater improvement)

根据二阶矩原理计算给定图像的二阶矩，也就是图像的中轴线(According to principles calculation of second moment second moment given image, that is the image of the central axis)
