N2 - Free space optical (FSO) communication systems have high bandwidth, cost effectiveness and can provide secure wireless communication service for users. They can also form asymmetric dual-hop cooperative communication links by multiplexing numerous radio frequency (RF) users by using amplify-forward transmissions over the FSO channel after converting to optical signals. In this study, an asymmetric dual-hop RF-FSO system is studied where the RF links follow the well-known Nakagami-m fading distribution and the FSO channel is efficiently modelled by the Málaga turbulence fading. The performance of the system is studied by deriving the closed-form expressions for the outage probability and ergodic channel capacity together with their asymptotic analysis at high signal-to-noise ratio. The numerical results are corroborated by Matlab analytical plots.
