On performance analysis of hybrid FSO/RF systems

In this work, the author investigate the performance of the hybrid free-space optical/radio frequency (FSO/RF) communication systems where RF links are subject to Nakagami-m distribution fading effects. The author derive the statistical characteristics of the hybrid FSO/RF systems in closed-form in terms of Meijer's G-function and the extended generalised bivariate Meijer's G-function. Then, the author rely on these new results to present the performance analysis of the selection combining diversity based on hybrid FSO/RF systems. Also, the author consider a Gamma–Gamma turbulence distribution under the impact of pointing errors and subject to both types of detection techniques (i.e. heterodyne detection and intensity modulation with direct detection (IM/DD)) in the FSO link. Computer-based Monte–Carlo simulations are proved the accuracy of the new analytical results.
