Abstract :
In this paper, we propose a novel two-step antenna selection algorithm for downlink Distributed Multiple Input Multiple Output (D-MIMO) systems. First, the distributed antenna cluster is selected based on maximum path fading, and then the antennas in the selected antenna clusters are chosen utilizing the permutation and QR decomposition (IC-PQRD) method. The analysis and simulation results show that our algorithm could greatly enhance the average channel capacity of the downlink distributed antenna systems. Furthermore, in the edge region of a cell, both the system capacity and symbol error probability (SER) are significantly improved due to the antenna cluster selection process. For in-cluster antenna selection in the second step, the IC-PQRD algorithm could largely improve the system outage capacity with low computational complexity and low SER.
