Relay-Assisted Mixed FSO/RF Systems Over Málaga- $\mathcal {M}$ and $\kappa $ – $\mu $ Shadowed Fading Channels

This letter presents a unified analytical framework for the computation of the ergodic capacity and the outage probability of relay-assisted mixed FSO/RF transmission. In addition to accounting for different FSO detection techniques, the mathematical model offers a twofold unification of mixed FSO/RF systems by considering mixed Malaga- $ {\mathcal {M}} / {\kappa }$ - ${\mu }$ shadowed fading, which includes as special cases nearly all linear turbulence/fading models adopted in the open literature.
