摘要
介绍了自同步扰乱器的工作原理,分析了m序列与自同步扰乱序列的关系,提出了利用解方程组法分析自同步扰乱序列的方法。同时利用Walsh变换求解方程组,大大减小了自同步扰乱序列分析的运算量。
This paper introduces the work principle of self-synchronizing scrambler, then analyzes the relation between m sequence and self-synchronizing scrambler sequence.It developes the method with resolving the (F(2)) equations to analyze self-synchronizing sequence,at the same time,which makes use of the fast-algorithm of Walsh transform .This algorithm greatly reduces the calculation quantity to analyze the self-synchronizing sequence.
