Distributed Multiple Input Multiple Output system (D-MIMO) becomes an attractive topic for increasing system capacity more efficiently. In this paper, the authors propose a novel two-step antenna selection algorithm for downlink D-MIMO systems. First, the distributed antenna cluster is selected based on maximum path fading, and then the antennas in the selected antenna cluster are chosen utilizing the Permutation and QR Decomposition (IC-PQRD) method for V-BLAST systems with Ordered Successive Interference Cancellation detection (OSIC).
