摘要
In this paper, we investigate the outage probability of a dual-hop, channel state information (CSI)-assisted amplify-and-forward (AF) multiple antenna relay network when interference is present at the relay. The source and the destination are equipped with multiple antennas and communicate with each other with the help of a single antenna relay. Transmit antenna selection is performed at the source for source-relay communication. Three receiver combining schemes namely, maximal ratio combining (MRC), equal gain combining (EGC) and selection combining (SC) are considered at the destination. Exact analytical expressions are derived for the outage probability of MRC and SC receiving while an approximate expression is obtained for EGC. Monte-Carlo simulation results are provided to complement analytical results and to demonstrate the effect of interference.
