载波恢复环的设计与分析

Analysis and Design of Carrier-Recovery Loop

在现代通信中，常常需要迅速、准确地恢复载波和提取解调信号．本文利用典型的基带调制再生型反调制环实现载波恢复．分析了环路的基本工作原理并结合环路的主要技术指标，给出了环路主要部件和参数的选取与设计．

In modern communication,it is often need to recover carrier and demodulate signal promptly and precisely. This paper implements carrier recovery by using a typical inverse modulated loop of base-band-modulated regeneration and analyzes the basic principle of the loop. In according to the specification of the loop,the design of the loop and main parameters are given in the paper.
