摘要

本文研究了近场通信中流体天线系统（FAS）的能量效率最大化问题。具体来说，我们考虑一个点对点近场系统，其中基站（BS）发射机具有多个固定位置天线，用户通过多个流体天线接收信号。我们的目标是共同优化BS的发射波束形成和流体天线在用户处的位置，以最大限度地提高能源效率。该方案基于交替优化算法，迭代解决波束形成和天线位置子问题。仿真结果验证了该算法的性能改进，验证了FAS的有效性。

Joint Beamforming and Antenna Design for Near-Field Fluid Antenna System

In this letter, we study the energy efficiency maximization problem for a fluid antenna system (FAS) in near field communications. Specifically, we consider a point-to-point near-field system where the base station (BS) transmitter has multiple fixed-position antennas and the user receives the signals with multiple fluid antennas. Our objective is to jointly optimize the transmit beamforming of the BS and the fluid antenna positions at the user for maximizing the energy efficiency. Our scheme is based on an alternating optimization algorithm that iteratively solves the beamforming and antenna position subproblems. Our simulation results validate the performance improvement of the proposed algorithm and confirm the effectiveness of FAS.
