On performance analysis of hybrid FSO/RF systems

Abstract

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.
