| 摘要: |
| 本文根据突发式数字通信快速锁相要求,提出一种位同步信号提取的新的快速全数字锁相环方案.它比一般数字锁相环捕捉速度最大可以提高N/2倍,且环路的同步时间与量化相位误差的矛盾也得到了解决,因而环路精度也大有改善.本文主要以一阶环为例讨论位同步信号提取. |

| Abstract: |
| This paper presents a new type of all digital phase-locked loop(ADPLL)used for extracting a bit-synchronous signal to meet the requirements of the fast phase-locked in burst digital communication.The fastest synchronous speed of the loop is increased N/2 than that of the general ADPLL.Phase error precision of the loop is improved largly with reducing contradiction of the synchronous time and phase quantized error. This paper discusses extraction of the bit-synchronous signal with a first-order ADPLL mainly. |
