摘要

研究了存在不完全信道状态信息时全双工(FD)中继的中断概率和吞吐量。我们考虑了一种放大转发(AF)协议协作通信系统,其中源节点在多个中继节点的帮助下与目标节点通信。在中继选择(RS)方案中,只选择接收端有效信噪比(SINR)最大的最佳中继。仿真结果显示了信道估计误差对全双工协同中继系统的影响,对实际实现的评估有一定的参考价值。

Analysis of full-duplex AF Relaying under Imperfect Channel State Information
This paper investigates the outage probability and throughput of full-duplex (FD) relaying with the presence of imperfect channel state information (CSI). We consider an amplify-and-forward (AF) protocol cooperative communication system where a source node communicates with a destination node with the help of more relay nodes. In the relay selection (RS) scheme, only the best relay which maximizes the effective signal-to-interference-and-noise ratio (SINR) at the receiver end is selected. Simulation results show the impacts of channel estimation errors on full-duplex cooperative relay system and are useful in the evaluation of practical implementations.
