摘要
Because the existence of feedback delay, channel estimation error and frequency reuse can severely impact the performance of relay system, the outage probability performance of a multi-antenna two-hop Amplify-and-Forward (AF) relay system with imperfect Channel State Information (CSI) and Co-Channel Interference (CCI) is investigated. Based on the beamforming (BF) model with feedback delay at source and estimation error at destination, we firstly obtain the equivalent output signal-to-interferenceplus-noise ratio (SINR) for the AF relaying. Then, we derive the analytical expressions for the Outage Probability (OP). The analytical results are verified through comparison with Monte Carlo simulations, where the effects of different channel parameters on the system's outage probability performance are also investigated.
