基于matlab实现经典算法GN，输入矩阵，输出社区结果(Implement the classic algorithm GN)

本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo，给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。 由于对于码块长较大的情形仿真需要较长时间，源码包也给出了部分分量码多项式的仿真结果，可直接用于绘图。 源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献，以及本人对通信系统中迭代译码过程分析技术综述的小论文，希望对大家有所帮助。(This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help.)

这个是模拟linux管理系统的子系统，用matlab编写的。(This is the child system of linux manage system, which writted by Matlab.)

This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.
