Antenna Selection for Spatial Multiplexing Systems Based on Complex Householder QR Factorization

In this paper, a novel antenna selection algorithm based on complex Householder QR factorization is proposed in wireless multiple input multiple output (MIMO) systems. It avoids the shortcoming of previous methods which need a mass of search over all possible subsets, has lower computation complexity and better performance. Simulation results demonstrate that the proposed antenna selection algorithm achieves excellent performance with linear receivers over fading channels.
