We present a novel relay selection algorithm in amplify-and-forward relay network with one source node, one destination, and multiple relay nodes. When the channel state information (CSI) of the first hop used for selection is outdated, closed-form expression for the system outage probability is derived. Then we propose a relay selection algorithm with assistance of the channel correlation coefficient, which aims at minimizing the system outage probability. The numerical simulation results show that the proposed strategy brings significant performance gain compared to the conventional partial relay selection strategy.
