Effects of co-channel interference on sum-rate based relay selection method for a dual-hop multiple full-duplex two-way wireless relaying networks

This paper investigates the co-channel interference effects on sum-rate based relay selection strategy. the investigation considers a dual-hop multiple full-duplex bi-directional wireless relay in the system model. according to analytical,asymptotic and the monte-carlo simulation results,sum-rate based relay section strategy outperforms the max-min based strategy. results also show that the co-channel interference degrades the achievable diversity order from n to 0 and also causes system coding gain losses in high signal-to-noise ratio regimes. on the other hand,the co-channel interference also severely affects the system achievable rate performance and degrades the performance curves at high snr regimes.
