摘要
本文提出了一种快速提取位同步的全数字锁相环方案。该方案通过对同步区、反相区以及快慢区的切换,有效地克服了同步时间与量化相位误差的矛盾。具有同步建立时间短、保持时间长、且同步精度高、抗干扰能力强等优点。
This paper presents a version of fas extrat ion bit-synchro- nization all digital phase-locked loop. This version can overcome efficiently contradiction between synchroniztion time and quantization phase error through the switchover of synchronization area, inverting phase area and fast-slow area. Its mcrits are that synchronization setting-up time is short, holding time is long, synchronization accuracy is high and anti-conference ability is strong.
