摘要

在本文中，我们研究了过时的信道状态信息(CSI)和同信道干扰(CCI)对双跳放大和转发(AF)多输入多输出(MIMO)中继网络中选择性组合发射天线选择(TAS/SC)性能的影响。分别导出了完美CSI和过时CSI情况下的停机概率的精确封闭形式和渐近表达式。仿真结果与理论分析吻合较好。研究结果表明，过时的CSI和CCI对具有TAS/SC的AF MIMO中继系统的中断概率有显著影响。

Performance analysis of TAS/SC in MIMO relay systems with outdated CSI in the presence of co-channel interference

In this paper, we investigate the impact of the outdated Channel State Information (CSI) and the Co-Channel Interference (CCI) on the performance of Transmit Antenna Selection with Selective Combining (TAS/SC) in a dual-hop amplify-and-forward (AF) Multiple-Input Multiple-Output (MIMO) relay network. We derive the exact closed-form and asymptotic expressions for the outage probability in the cases of perfect and outdated CSI, respectively. The simulation results match the theoretical analysis well. The findings suggest that the outdated CSI and CCI have significant impacts on the outage probability of an AF MIMO relay system with TAS/SC.
