Abstract :
This paper investigates a free space optical (FSO) communication system with multiple user pairs sharing a single relay over atmospheric turbulence induced fading channels effected by path loss. Multiuser diversity is achieved by applying various scheduling schemes at the relay. The performance of various scheduling schemes based on selection combining (SC) diversity and switched diversity are evaluated for the considered dual-hop, bi-directional, half-duplex relay system with network coding. Closed form expressions for the outage performance for different scheduling schemes have been derived.
