摘要
用自适应比特泄漏扩散由指针调整引起抖动是衰减通信抖动的一种重要的手段,结合SDH中TU-12指针调整的特点,重点讨论一种自适应比特泄漏电路设计以及比特泄漏率的软件计算方法,并给出了SDH结合抖动中四种测试码的理论计算结果和芯片实测结果.
Self-adaptive bit-leaking diffusion jitter caused by pointer justification is an important method for attenuating jitter in Synchronous Digital Hierarchy (SDH). According to the characteristic of Tributary Unit(TU-12) pointer justification, a kind of self-adaptive bit-leaking circuit design and a method for calculating bit-leaking rate is discussed in detail. And theoretical and experimental results of four tests codes for combined jitter measurement in SDH are showed in the paper.
