AI 中文摘要
流体天线阵列（FAAs）可在规定孔径内重新配置有限数量的辐射端口。然而，在紧凑孔径中，基于信道的端口放置可能导致端口聚集，增强互耦，降低辐射条件，增加源电压需求，并产生不均匀的电流负载。本文研究下行链路多用户波束成形，联合优化端口放置与电流域传输。一种电磁引导图网络从信道观测中预测端口布局，并利用几何和互阻抗信息对其进行优化。训练目标同时考虑通信性能与电磁可行性，且所有方法采用统一评估流程。结果表明，在统一可行性标准下，所提方法可在通信速率、电流负载和配置延迟之间实现可控权衡。
英文摘要
Fluid antenna arrays (FAAs) reconfigure a finite set of radiating ports within a prescribed aperture. In compact apertures, however, channel-driven placement may cluster ports, strengthen mutual coupling, degrade radiation conditioning, increase source-voltage demand, and produce uneven current loading. This paper studies downlink multi-user beamforming with jointly optimized port placement and current-domain transmission. An electromagnetic-guided graph network predicts port layouts from channel observations and refines them using geometric and mutual-impedance information. The training objective jointly considers communication performance and electromagnetic feasibility, while a common evaluation procedure is applied to all methods. The results show that, under a common feasibility standard, the proposed method provides a controllable tradeoff among communication rate, current loading, and configuration latency.
