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).

matlab code for filterbank

计算近似熵、改进的样本熵及优化的模糊熵,均为matlab下编辑的程序，是很好的复杂度指标(approxy entropy, sample entropy and fuzzy entropy matlab code )

插值和拟合在数学模型的求解中非常重要，本程序给出了一些典型算法。(Interpolation and fitting mathematical models to solve the very important, this procedure gives some typical algorithms.)

zero forcing detection methods for MIMO system

讲述了一种基于RS吗的软扩频通信及其simulink仿真(About you based on the soft RS simulink simulation of spread spectrum and its)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get some diversity gain.)

说明：  MATLAB椭圆你和函数，还好吧，但是我没太看懂~(MATLAB elliptic function you and also Well ~)

说明：  一维阵列波束形成，波束指向图，可调整各种参数(beamforming)

这是一个用simulink编程，可以来实现QAM，里面有多个程序，如果毕业设计是关于这个内容的，可作为参考(This is a simulink programming, can come to realize QAM, there are a number of procedures, if the graduation project is on the content, may be used as reference)
