| 英文摘要: |
| 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 fading, the proposed algorithm decreases enormously the computational complexity. Based on the characteristics of distributed systems, an improved particle swarm optimization (PSO) has been proposed for the antenna selection after the RAU selection. In order to apply the improved PSO algorithm 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 capacity with low computational complexity. |
