对于Ldpc码，测试其校验矩阵H有无4环的存在，避免因为存在4环影响性能(For Ldpc code, test whether the check matrix H of the existence of loop 4, loop 4 to avoid because of the impact of performance)

partial differential equation 2 by matlab

这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波的OFDM，运行此程序需2分钟－3分钟的时间。 (This is a very good CP for OFDM-based maximum likelihood symbol timing synchronization and carrier synchronization of the MATLAB simulation program, after I read the absorption of classical literature in depth, repeated programming and debugging derived, code refining orderly, absolute no mistake, this process has been synchronized simulation curve is fully consistent with classical literature. Tongren have read this procedure will definitely benefit! Spared the outcome here, especially to upload to share with you friends. Tongren also welcome to provide more excellent program. Documentation required as a result of N = 1024 sub-carrier OFDM, to run this process will take 2 minutes-3 minutes.)

说明：  本程序是用matlab开发的扩展Kalman Filter(this procedure is used Matlab development of the extended Kalman Filter)

使用matlab编写的，制作gif的小程序，可以更换背景和显示的图片。(Use matlab, making gif small program that can replace the background and display pictures.)

本文件是是我们组参加2013全国大学生数学建模的比赛论文，荣获全国2等奖，不信可以百度下，包括所有论文程序的附件，完整版，程序包括matlab的程序，有神经网络的程序，基于小波分析的程序，也有基于vissim交通流的仿真程序包！相当给力！程序阅读和说明都在上面！(This document is our group to participate in the 2013 national college tournament mathematical modeling papers, won the two prize, do not believe you can Baidu, the program includes all papers attachments, full version, matlab procedures, including procedures, a neural network program, Based on wavelet analysis procedures, there are also based vissim traffic flow simulation program package! Quite a force! Read the instructions and procedures are in it!)

说明：  实现duffing方程的绘图，为工程上观察duffing混沌现象给出一个仿真的方法 (give a way to drew the picture of duffing)

说明：  MATLAB的实用经典程序3，可使初学者在短时间内较快掌握MATLAB中的一些基本函数(MATLAB utility classic program 3 will enable beginners to master quickly in a short time some of the basic function of MATLAB,)
