摘要

本文概述了互天线耦合对大规模MIMO的影响及其对获得能量效率和功率分配方案的影响。随着大规模MIMO下行链路合作的日益普及，天线阵列的设计和制造变得越来越具有挑战性。导出了天线互耦影响下的多目标最优功率分配策略表达式。在考虑或忽略联合天线耦合的情况下，数值分析和仿真结果表明，优化后的平均信道功率与实测结果存在较大差距。结果表明，需要仔细考虑天线共耦合效应，以获得单个速率或总和速率能力和正确的最佳功率分配策略。计算机模拟实例支持这一论点。

Dynamic Power Allocation for Cooperative Multi- Antenna Networks in Presence of Mutual Coupling

This paper provides an overview of the influence of mutual antenna coupling on the massive MIMO and its effects on gaining energy efficiency and power allocation schemes. As massive MIMO downlink cooperation becomes more prevalent, it becomes challenging to design and manufacture antenna arrays. We derive expressions for the multi-objective optimum power allocation strategy under the influence of mutual antenna coupling. When joint antenna coupling is taken into account or ignored, the numerical analysis and simulation results indicate a substantial gap in the measured results for the optimized average channel power. The results suggest that antenna common coupling effects need to be carefully considered to obtain individual rate or sum-rate capability and the right optimal power allocation strategy. Computer simulation instances back this argument.
