一个简单的m序列产生函数，通过调用primpoly获得本原多项式，然后通过移位循环寄存器产生所需要的序列。自相关图形上能看到峰值旁瓣电平(PSL)和积累旁瓣电平(ISL)。-A simple code for generate m-series pseudo-random sequence based PRIMPOLY function　which we get the prime polynomials first,then we get the feedback connect coefficient of the cycle shift registers which generate m-series sequency. the PSL and ISL of autocorrelate function is computed on the figure.
