Miaowen Wen, Xiang Cheng, Anpeng Huang, Bingli Jiao · IEEE Communications Letters · 2012
In this letter, the asymptotic performance of channel state information-assisted amplify-and-forward multihop relaying with co-channel interference (CCI) at both relays and destination over Nakagami-m fading channels is investigated. Assuming integer fading parameter m for source → relay → destination links and arbitrary fading parameter m for CCI links, we derive closed-form expressions for bit error rate of the system at high signal-to-interference-plus-noise regime and characterize the diversity order and coding gain achieved by the system. Simulation results are provided to validate the analysis.
