摘要

本文研究了单源、单目的、多中继以译码转发(DF)方式工作的混合射频自由空间光(RF/FSO)通信系统的误码率性能分析。分析和比较了上行链路(RF跳后是FSO跳)和下行链路(FSO跳后是RF跳)的几种中继方案。RF链路受中上衰落和加性高斯噪声的破坏，而FSO链路受γ - γ闪烁，其中由背景噪声和暗电流产生的光子遵循泊松分布。

Performance analysis of up-link and down-link mixed RF/FSO links with multiple relays

This paper targets the bit error rate (BER) performance analysis of mixed radio-frequency free-space optical (RF/FSO) communication systems with a single source, single destination and multiple relays operating in the decode-and-forward (DF) mode. Several relaying scenarios are analyzed and compared for both the up-link (RF hop followed by an FSO hop) and the down-link (FSO hop followed by an RF hop). The RF links are subject to Nakagami fading and corrupted by additive Gaussian noise while the FSO links are subject to gamma-gamma scintillation where the photons generated by the background noise and dark currents follow the Poisson distribution.
