Multihop communications over CSI-assisted relay IM/DD FSO systems with pointing errors

In this paper, the end-to-end performance of a multihop free-space optical system with amplify-and-forward channel-state-information-assisted relays using intensity modulation with direct detection technique over Gamma-Gamma turbulence fading with pointing error impairments is studied. More specifically, novel closed-form expressions for the moment… CONTINUE READING
