摘要
本文介绍了C-4/E4映射的并行处理方法,通过理论分析和计算机仿真对并行映射的调整抖动进行了分析,分析表明常规的并行映射处理会对支路抖动性能造成恶化。本文最后给出了一种改进的并行映射处理方法,这种方法不需要高速SDH155.52MHz时钟,而其抖动性能与串行处理方式相同。
Parallel processing techniques are introduced for C-4/E4 mapping in SDH. Its performance of stuffing jitter is analyzed both in theory and by computer simulation,which shows that the normal parallel processing method will degrade the jitter performance. An improved parallel processing method is presented in the paper. The novel method needs no 155. 52MHz clock while its jitter performance is just the same as serial mapping processing.
