摘要

本文分析研究了采用雪崩光电二极管(APD)的放大前向(AF)串行中继自由空间光学(FSO)系统在伽玛-伽玛分布模拟的大气湍流中的性能。假设子载波二相移键控(SC-BPSK)信令，并在每个中继节点上使用APD进行信号检测和放大。考虑大气湍流和APD接收机噪声的影响，采用矩匹配方法解析导出了中断概率和平均误码率的封闭表达式。通过蒙特卡罗仿真验证了分析结果，分析结果与仿真结果吻合较好。

APD-based amplify-and-forward serial relaying FSO systems over Gamma-Gamma channels

This paper analytically study the performance of amply-and-forward (AF) serial relaying free-space optical (FSO) systems employing avalanche photodiodes (APD) in atmospheric turbulence modelled by the Gamma-Gamma distribution. The subcarrier binary phase-shift keying (SC-BPSK) signalling is assumed and at each relay node, an APD is used for signal detection and amplification. Closed-form expressions of outage probability and average bit error rate (BER) are analytically derived taking into account the impact of atmospheric turbulence and APD receiver noise by using the moment matching method. The analysis is verified by Monte-Carlo simulation and a good agreement between the analytical and simulation results is confirmed.
