This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

一个pid仿真例子，有程序和仿真模拟图，可以直接应用，希望有用！(A simulation example of a pid, have procedures and simulation map, can be applied directly, I hope useful!)

Map matching is the process of assigning user s location to the nearest node one a network. Three algorithms of map matching, point to point, point to line and line to line are presented in this document.

本程序是雷达恒虚警模块的仿真程序，可用于雷达CFAR检测(This procedure is a radar CFAR module simulation program can be used for radar CFAR detection )

图像去噪中常用的RLO和对数模型源代码 自己编的 效果还可以(RLO commonly used in image denoising and model number of the effect of the source code can be compiled their own)

对于卫星系统的优化，目前比较前沿的是基于多学科优化(MDO)的方法，文中重点对此方法进行了介绍。(For the satellite system optimization, more cutting edge is based on the current multi-disciplinary optimization (MDO) methods, the paper focus on this method were introduced.)
