Performance analysis of multi-source multirelay wireless networks with co-channel interference

The performance of multi-source multi-relay wireless networks based on a joint source-relay-selection scheme is investigated over Rayleigh interference-limited fading channels. The tight lower bound and asymptotic expressions for the outage probability are derived and the diversity order of the system with/without co-channel interference is further discussed. Simulation results are presented to demonstrate the validity of the theoretical analysis.
