Analysis of Dual-Hop AF Relay Systems in Mixed RF and FSO Links
Abstract
We analysis the performances for the dual-hop fixed gain amplify-and-forward (AF) relay systems operating over mixed radio-frequency (RF) and free-space optical (FSO) links. The RF link is subject to Rician fading and the FSO link experiences Gamma-Gamma turbulence fading. We derive the closed-form expressions for the outage probability and the average symbol error rate in terms of the Meijer's G function.All analytical results are corroborated by simulation results and the effects of fading parameters on the system performances are also studied.
