Fast algorithm for antenna selection in MIMO systems based on minimum error rate

In this paper, a fast antenna selection algorithm is proposed in wireless multiple input multiple output systems. The algorithm makes use of an efficient recursive QR factorization for selecting the sub-optimal antenna subset in terms of minimum error rate. The proposed algorithm decreases the computational complexity greatly, and improves the performance of the linear receiver. Simulation results demonstrate that the proposed antenna selection algorithm achieves excellent performance under uncorrelated and correlated channel.
