In the promising cooperative communication systems,network performance is mainly affected by interference instead of noise.In this paper,we consider the performance degraded by the Poisson filed interference in the dual-hop relay channels.We focus on the discussions of error outage probability(EOP)performance with a selective-decode-and-forward(SDF),amplify-and-forward(AF),or fixed-decode-and-forward(DF)cooperation protocol.Finally,the simulation results present the performance with different cooperation protocols with interference in a Poisson field.
