论文摘要
在本文中，我们研究了由射频（RF）和自由空间光学（FSO）链接组成的双跳继电器系统。使用解码（DF）继电器用于集成第一个RF链接和第二个视线FSO链接。假定RF通道受到最近提出的Fisher-Snedecor褪色模型的约束，该模型被证明是在现实的无线通信方案中进行建模方便的。 FSO通道受γ-伽马分布的大气湍流的影响。中断概率的表达被得出并用来呈现数值结果。基于提出的结果，研究并讨论了各种RF和FSO通道参数对整体系统性能的影响。
In this paper, we investigate a dual-hop relaying system, composed of radio frequency (RF) and free-space optical (FSO) link. Decode-and-forward (DF) relay is employed to integrate the first RF link and the second line-of-sight FSO links. The RF channel is assumed to be subject to recently proposed Fisher-Snedecor fading model, which was shown to be convenient for modeling in realistic wireless communication scenarios. The FSO channel is affected by Gamma-Gamma distributed atmospheric turbulence. Expression for the outage probability is derived and utilized to present numerical results. Based on presented results, the effects of various RF and FSO channels parameters on the overall system performance are examined and discussed.
