自己刚学习时练习用的软件，挺好的，如果有初学以尝试下者可(Their practice with just learning the software, very good, if beginners to try the next may)

该程序将常用的线性码、循环码、汉明码、BCH码等，配上常用的二进制相键控调制BPSK搭建成仿真系统，对它们的传输特性进行了仿真！(The program commonly used linear codes, cyclic codes, Hamming, BCH codes, coupled with the commonly used binary phase shift keying modulation BPSK built into the simulation system for their transmission characteristics are simulated!)

本代码是ja-sw 矢量磁滞模型的混合模型的代码，有两部分一部分是ja模型，另一部分是sw模型，两者混合变为矢量磁滞模型(This code is ja-sw vector hysteresis model hybrid model of the code, there are two parts ja model part, the other part is sw model, a combination of both into a vector hysteresis model)

Wiener filter based on tracking a priori SNR using Decision-Directed method, proposed by Scalart et al 96.
