Beamforming Design for Integrated Sensing and Communication Based on Fluid Antennas
摘要
Abstract
This paper proposes a novel joint optimization framework for dynamic beamforming and antenna positioning in fluid antenna-enabled integrated sensing and communication systems.The study aims to maximize the effective sensing beampattern gain toward the target direction while satisfying user communication signal-to-interference-plus-noise ratio constraints and base station power limitations.To address the non-convex optimization challenge arising from the strong coupling between beamforming matrices and antenna positions,an efficient alternating optimization framework is developed.Specifically,the beamforming optimization is first transformed into a semidefinite programming problem through penalty-based rank constraint relaxation.Subsequently,sequential convex approximation techniques are employed to iteratively optimize the antenna positions.Simulation results demonstrate that the proposed scheme achieves significantly higher beampattern gains than conventional fixed-position antenna designs.关键词
