摘要

针对大气湍流在星地激光通信接收端引起的光强闪烁现象会影响通信质量的问题，研究一种基于增益竞争的光功率均衡系统。实验验证接收功率波动会增加通信误码率，研究增益竞争下均衡系统的静态输出曲线并对动态时域信号进行均衡性能测试，实验证明该系统可以将动态信号的功率波动范围压缩至4 dB。

Abstract

Aiming at the problem of light intensity scintillation caused by atmospheric turbulence at the receiver of satellite-ground laser communication will aff ect the communication quality

an optical power balance system based on gain competition was studied.The experiment verifi ed that the received power fl uctuation increased the communication bit error rate.The static output curve of the equalization system under gain competition was studied and the equalization performance of the dynamic time domain signal was tested.The experimental results showed that the system could compress the power fl uctuation range of the dynamic signal to 4 dB.
