SDH中恢复四次群时钟的自适应预测法
摘要
同步数字系列(SDH)中的指针调整引入了8bit或24bit的大幅度抖动
为了处理这一抖动
提出了一种数字化处理方法———自适应预测法
可以作为预处理方法应用于SDH中的四次群时钟恢复。文章主要以从STM 1中恢复四次群信号为例
对该方法的应用做详细介绍
并对其性能进行分析。
Abstract
Pointer adjustments bring 8 bit
or even 24 bit jitter in synchronous digital hierarhy (SDH). In order to smooth the jitter
this paper presents a digital processing method
self-adaptive prognostication method
which can be applied as a preliminary processing method to regenerate the fourth order (E4) clock in SDH. This paper uses the example of regenerating the fourth order (E4) signal from STM-1 to introduce in detail the application of this method and its performances.
