Abstract: | An antenna selection algorithm based on large-scale fading between the transmitter and receiver is proposed for the uplink receive antenna selection in distributed multiple-input multiple-output ( D-MIMO) systems.By utilizing the radio access units ( RAU) selection based on large-scale fa-ding , the proposed algorithm decreases enormously the computational complexity .Based on the characteristics of distributed systems , an improved particle swarm optimization ( PSO) has been pro-posed for the antenna selection after the RAU selection .In order to apply the improved PSO algo-rithm better in antenna selection , a general form of channel capacity was transformed into a binary expression by analyzing the formula of channel capacity .The proposed algorithm can make full use of the advantages of D-MIMO systems , and achieve near-optimal performance in terms of channel ca-pacity with low computational complexity . |
