We propose a novel antenna selection algorithm for amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay networks. Assuming equal-power allocation across the activated antennas, we iteratively select the antenna pairs to greedily maximize the network capacity in closed-form expressions. Simulation results show that our algorithm greatly outperforms the existing schemes, with the gain being more pronounced when the noise at relay nodes is relatively high. Moreover, from the… CONTINUE READING
