摘要

针对空间激光通信接收功率低的问题，文章设计并实现了具有高接收灵敏度的实时化空间激光脉冲位置调制(PPM)通信系统，该系统的传输速率为800 Mslot/s。实验结果表明，当使用了掺铒光纤放大器(EDFA)和光学滤波器后，在接收光功率为-58.3 dBm的情况下，该系统的纠前误码率(BER)为1.4E-4，系统具有超高的灵敏度。

Abstract

Aiming at the low receiving power of space laser communication

a real-time space laser Pulse Position Modulation (PPM) communication system with high receiver sensitivity is designed and implemented in this paper and the transmission rate of this system is 800 Mslot/s. The experimental results show that

after using Erbium Doped Fiber Amplifier (EDFA) and optical filter

under the condition of -58.3 dBm optical input

the Bit Error Rate (BER) of the system before error code correction is 1.4E-4 and the system has ultra-high receiver sensitivity.
