Performance Analysis of TAS/MRC in MIMO Relay Systems With Outdated CSI and Co-Channel Interference
Jing Guo, Changxing Pei, Hong Yang · IEEE Transactions on Wireless Communications · 2014
In this paper, we investigate the impact of outdated channel state information (CSI) and multiple co-channel interferers (CCI) on the performance of transmit antenna selection/receiver maximal-ratio combining (TAS/MRC) in a dual-hop amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay network. The tight lower bound and asymptotic expressions for the outage probability are derived. The diversity order of the system with/without outdated CSI in the presence of multiple CCI is further discussed. Numerical and simulation results are presented to validate our analysis and to demonstrate the effect of outdated CSI and multiple CCI on the system performance.
