说明：  BD-OFDM的接收和发射，是用Matlab编程实现的++matlab，程序比较简洁，易懂。(BD-OFDM receiver and the launch is the use of Matlab programming of the++ matlab, procedure is simple and easy to understand.)

最短径问题的课件，可以用MABLAB源代码编写(Raily)

Matlab软件在通信仿真中的应用，适合初学者参考。文件为pdg格式，需下载超星浏览器才可阅读。(Matlab simulation software application in communication, suitable for beginners. File format for PDG, need to download the chaoxing browser.)

波束成形在多天线MIMO环境下的，接收端合并与检测技术(Under the multi-antenna beamforming MIMO environment, merged with the receiver detection technology)

BER of the VUS-MUMIMO-SM Uplink System - Rayleigh( BER of the VUS-MUMIMO-SM Uplink System- Rayleigh)

This M-File imports data from binary *.dat files, created with PSpice 6.0 (DOS), 9.1 (Student), and 10.0.3. If you are using newer versions of PSpice, you might need to adjust the code.

说明：  HOUGH变换及用于SAR动目标检测的matlab程序！(HOUGH Transform and its implemention in the SAR moving target detection )

利用函数MadHG生成规则LDPC码的校验矩阵H，其行重为6,列重为3,行数为列数一半(行数越大越好)，H中任意两列没有围长为4的圈，并得到H对应的生成矩阵G，可以保证mod(G*H ,2)=0。使用方法为:[H,G] = MadHG(m,n,x),x= 1(得到的G左半部分为单位阵) or 2(G右半部分为单位阵),(use function MadHG Generation rules LDPC check matrix H, re-6, series of three, out for a few half of the number (A bigger the better), H 2 arbitrary no girth of the four circles, H counterparts and with the formation of matrix G, we can be assured of mod (G* H, 2) = 0. To be used : [H, G] = MadHG (m, n, x), x = 1 (the G part of the Left Front units) or 2 (G right half of the units RUF),)

duffing系统各参数变化引起的分岔,如激励频率，线性参数k1，还能计算李亚普洛夫指数(duffing system bifurcation parameter variations)

根据干信比调节，生成指定带宽的调频噪声，产生噪声调频信号(According to the dry letter than regulation, to generate a specified bandwidth FM noise, noise FM signal)
