高速数字传输中的帧同步提取分析

本文讨论具有帧结构的高速数字流的帧同步提取技术。从帧同步器方案的最佳参数设计出发,以误码性能为主要目标,本文较系统地提出了一套有关帧同步过程的基本概念和分析方法,并导出在各种情况下的统计关系及重要结论。本文还以美国陆地卫星TM数据流为例,特别阐述了复帧结构情况下的帧同步提取及其最佳参数设计。

Analysis of the frame-syne extraction in high rate digital transmission

This paper refers to the frame-sync extraction technology of high-ratedigital stream with a frame configuration. From the viewpoint of the optimumparameter design of a frame-sychronizer scheme, leading to a nice bit-error per-formance, this paper puts forward a set of systematic concepts and analytical methods,and derives the statistic relationships and essential conclusions in various cases.Furthermore, this paper particularly describes the optimum parameter design offrame-sync extraction in the case of multi-frame structure with an example ofthe TM data. tream of the U. S. Landsat satellite.
