Performance Analysis of Opportunistic Relaying in Rayleigh Fading Channels with Interference
Yin Jing · Beijing Youdian Xueyuan xuebao · 2010
Because of interference between both the relays and the destination,the two opportunistic relaying protocols are proposed to minimize the outage probability according to whether the direct transmission is considered or not. Moreover,if the direct transmission is taken into account,maximal ratio combining is deployed at the destination to combine the direct transmission and relay transmission. The outage probabilities of the protocols are derived over the independent non-identically distributed Rayleigh fading channels. Simulations validate our analysis. Furthermore,in terms of outage probability,opportunistic relaying considering the interference is better than that without considering the interference,and opportunistic relaying with a direct link outperforms that without a direct link.
