Abstract :
In this paper, the performance of a dual-hop amplify-and-forward (AF) relay system under the joint impact of feedback delay and multiple co-channel interference (CCI) at the relay node is studied with the kth worst partial relay selection (PRS) protocol. In our analysis, the closed-form expression of the outage probability is derived. Further, the tight lower bound and asymptotic expression of outage probability is given and the diversity order of the system with CCI and feedback delay is obtained at high signal-to-noise ratio (SNR) regime. Finally, Monte-Carlo simulation results are presented to verify the validity of our theoretical analysis.
