帧同步扰码器的并行化技术

Parallel Techniques for Frame Synchronous Scrambler

在高速传输系统如ＳＤＨ中，需要用到并行扰码技术。而且提出了一种扩展矩阵的方法，使传统的矩阵法可以用来实现任意路数的并行扎码器。本文还提出了一种新的实现并行扰码的方法──延时因子法，由此实现了ＳＤＨ八路并行扰码器。

In high speed transmission system such as SDH,parallel scrambling technique is required. This paper presents a method of expanding matrix,which makes the traditional matrix method capable of realizing parallel scramblers of any size.A novel method called delay operator method is also described in this paper.The 8-bit parallel scrambling circuitry of SDH has been realized with the two methods.
