摘要

指针调整会在同步数字系列（ＳＤＨ）网中引入非常大的抖动．本文在分析比较了常见的两类指针泄漏方法的基础上，提出了一种新的抑制指针调整抖动的方法———平滑相位泄漏法．此方法有效地解决了泄漏的量化抖动问题以及复杂的泄漏控制问题．本文通过理论分析和计算机仿真比较了平滑相位泄漏方法与理想滤波的性能，并给出了此方法对不同指针测试序列的抖动抑制性能

Abstract

Pointer adjustment in SDH network will induce large jitter in the recovered tributaries.Based on the traditional pointer leaking techniques

a novel method named Smooth Phase Leaking is presented in the paper for the cancellation of pointer adjustment jitter.It greatly reduces the quantization jitter in pointer leaking and also the complexity of leaking control.The paper compares the performance of this method with that of an ideal filter through theoretical analysis and simulation.Performance of the method on those pointer testing patterns is also given.
