本程序及链路是模拟了瑞利信道下，用RLS算法还原出发送端的的有效信号。通过simulink实现，同时调用RLS的m函数。(This procedure and the link is simulated Rayleigh channel, the to restore valid signal to the sending end of the RLS algorithm. Simulink realization, while m function call RLS.)

It can be applyed forthe Spectral Element Method conbined finite element and spectral method to solve the 2D wave equation.as a pecial case is SH. dynamic fault with slip weakening is considered either.
