Abstract

To increase spectral and power efficiencies, network coverage, and reduce outage probability, this study investigated the end-to-end performance of a coded dual-hop RF/FSO wireless communication system that operates across both Nakagami- $m$ fading and Malaga- $\mathcal {M}$ atmospheric turbulence channels and is supplied with an amplify-and-forward semi-blind energy harvesting fixed-gain relay in order to increase spectral and power efficiencies, network coverage, and outage probability. We examine the use of CSOC codes at the source and a majority logic decoding method (MLGD) at the destination. Interestingly, our goal is to obtain an average bit error probability analytically by accounting for various interferers in the first hop as well as residual hardware impairments at the relay and destination receivers. As a consequence, the decoding method used in this investigation was shown to be adequate for the SWIPT/TS-assisted RF/FSO-coded AF cooperative communication system, requiring excellent accuracy while having a low computational cost.
