Analysis of False Lock in Phase Recovery Loop for LEO Micro-Satellite Burst-Mode Communication System

本文对LEO小卫星突发数据通信系统中载波恢复环路的误捕获现象进行了分析与计算机仿真 ,并根据分析与仿真的结果提出了一种实用的抗误捕获设计方法 .本文的分析结果在实际系统测量中得到了验证 ,对于类似系统的抗误捕获设计与分析有一定的实际意义 .

This paper presents a compute-aided analysis of false lock in phase recovery loop for LEO micro-satellite burst-mode communication system, based on which a method is set up for anti-false-lock design. The measurement of an actual burst-mode communication system proves the validity of the method of analysis and design.
