The performance of a dual-hop mixed FSO/RF system with fixed-gain relaying is studied under direct detection and heterodyne detection techniques. The FSO link is modeled using the Fisher-Snedecor F distribution, while the RF link experiences kappa - mu shadowed fading. Closed-form approximate expressions for various performance metrics are derived using the bivariate Fox's H function, and asymptotic analysis is performed at high signal-to-noise ratio. Numerical results and Monte Carlo simulations validate the derived approximate expressions.
We investigate the performance of a dual-hop mixed free space optical (FSO) /radio frequency (RF) system with fixed-gain relaying under direct detection and heterodyne detection techniques. The FSO link is modeled by the Fisher-Snedecor F distribution, which matches well with the experimental data under weak-to-strong turbulence regimes. The RF link experiences kappa - mu it shadowed fading, which unifies popular RF fading models. The kappa - mu shadowed distribution is approximated by an alpha - mu. distribution. Capitalizing on this approximation, closed-form approximate expressions for the cumulative distribution function, the average bit error rate of different modulation schemes, and the ergodic capacity are derived in terms of the bivariate Fox's H function. Moreover, asymptotic analysis is carried out at a high signal-to-noise ratio to further illustrate the obtained diversity order and the influence of system and channel parameters. Numerical results and Monte Carlo simulations are presented to validate the derived approximate expressions. (C) 2022 Optica Publishing Group
