去除图像中的栅格噪声，使图像更加清晰，更加美观(Remove the grid in the image noise, make the image more clear, more beautiful )

cpio源码,cpio2-11,不要钱了，随便看看(cpio code)

说明：  基于RFE-SVM进行两类的特征提取算法，能够提取出最佳的变量，已经经过测试，绝好的算法(two kinds of feature extraction algorithm based on RFE-SVM, it can extract the best variables,it has been tested,it is the best algorithm)

这是用matlab实现的多站定位系统性能仿真的源程序，希望对研究定位的人有所帮助！资源共享，也希望有关 于无源定位、多普勒信息提取方面代码的人共享一下，一起进步！(This is achieved using matlab multi-station positioning system performance simulation of the source, I hope the study will help position the person! The sharing of resources, but also on the passive positioning, Doppler information extraction area to share some code with the progress!)

说明：  （蒙特卡洛方法） 求出四分之一圆占正方形的比例。随机投点P(x,y)于正方形，π/4的近似值为落在四分之一圆内的点数与总投点数的比值。随机投点次数分别为10000次和50000次，计算π的近似值。 ((Monte Carlo method) are obtained accounting for a quarter of a round square ratio. Voted random point P (x, y) in the square, π/4 for the fall quarter of the approximation of the points won and the ratio of the total vote points. The number of random points, respectively, voted for the 10000 and 50000 times, the calculation of the approximation of π.)

A QPSK simulation using simulink. very useful to understand the scheme at every level of QPSK modulation.

一个PSO算法历程，有详细的注释，及相关演示过程。采用了基本PSO、权重优化、最大速度法三种（去掉代码中的相关行的注释即可使用）。(PSO algorithm is a process, detailed notes, and related presentation process. With the basic PSO, weight optimization, the maximum speed law of three (remove the code related to the comment line can be used).)

一种有效的数据预处理方法，主要用于matlab中，sar成像中(data processing)

this is matlab code for estimating the static linear system with Recursive Least Squre that is written by matlab 7.0. Here we want to estimate the below function: 1 - u^2 + 2*u^3 +u^5 +3*u^7 these are 2 files : without noise and with noise finally,there are plots for showing results.

压缩感知的算法，时间比较短，精度比较高。谢谢(Compressed sensing algorithm, the time is short, accuracy is relatively high. Thank you)
