m序列发生器SSRG和MSRG的研究

Study of m Sequence Generator SSRG and MSRG

首先分析得出由于两者的反馈输出关系不同,m序列发生器SSRG和MSRG在同种本原多项式条件下产生不同序列,且本原多项式下构架的SSRG和与其对偶多项式下构架的MSRG可使两者具有相同的反馈输出关系.由此,利用本原多形式与其对偶多形式的镜像对称特性得出一种简单的寻找生成同种序列的SSRG和MSRG的方法,及同种本原多项式下生成不同SSRG和MSRG伪码序列的方法.

That m-generators as SSRG and MSRG can export different sequences with the same primitive polynomial is firstly educed because of their different feedback output form,and SSRG which is generated by primitive polynomial can have the same feedback output form with MSRG,which is generated by dual polynomial.On the basis of the conclusion above,utilizing the dual character of primitive polynomial and its dual polynomial,the paper proposes a simple method to find out SSRG and MSRG which can export same sequences,and a method to generate different Pseudo-code sequences by same primitive polynomial.
