Abstract :
Based on accurate distributed multiple input multiple output (D-MIMO) downlink multiuser correlation channel model, a low complexity algorithm are proposed for joint transmit-receive antenna selection. By defining new metrics of uncorrelation and centrality, the sum rate performance of the proposed algorithms is comparable to the decremental algorithm with significant computational complexity reduction. The simulation results have proved our conclusion.
