Asymmetric mixed RF/FSO relaying over α-μ fading channel

Rapid increment in broadband networking needs has attracted researchers towards FSO systems. In this paper, relaying technique is proposed in FSO systems for increasing the link reliability. Present research work aims at analyzing a mixed RF/FSO system modeled as α-μ distributed fading. As suggested in the literature, α-μ distribution has the capability to generalize any fading scenario and distribution parameters provide better control on fading conditions. Finally, outage probability and average bit error rate closed form expressions have been derived and verified via computer based simulation.
