Transmit without regrets Online optimization in MIMO-OFDM cognitive radio systems

本代码讲了在matlab中实现数据的预处理的方法（包括标准化变化）等(The M codes describe how to pre-treat the datas in matlab (including the standardized convertion) etc.)

S－函数是System function 系统函数的简称，是指采用非图形化（即计算机语言，而非Simulink 系统模块）的方式描述的功能模块。在MATLAB 中，用户除了可以使用MATLAB 代码编写S－函数以外，还 可以使用C、C＋＋、FORTRAN 或Ada 语言编写S－函数，只不过用这些语言编写程序时需要用编译器生成 动态连接库（DLL）文件，然后在Simulink 中直接调用(S-function System Function system function, refers to the use of non-graphical (ie computer language, rather than the Simulink system module) way described functional modules. In MATLAB, the user can use MATLAB code to write the S-function outside can use C, C++, FORTRAN or Ada language preparation of the S-function, only in these languages ​ ​ to write programs need to use the compiler to generate dynamic link library (DLL ) file, and then called directly in Simulink)

实现了RS（26,20)译码器，用Matlab实现的，可以纠正3个随机错误(Implements RS (26,20) decoder, implemented using Matlab, random errors can be corrected 3)
