FA辅助通感一体化安全通信系统的波束成形设计
Beamforming Design of FA-aided Secure Integrated Sensing and Communication System
摘要
Abstract
This paper investigates fluid antenna(FA)array-aided secure integrated sensing and communication(ISAC)system design for addressing critical requirements of physical layer security(PLS)and ISAC in 6G mobile communications.By jointly optimizing base station precoding matrix,artificial noise vector,and FA position distribution,we establish a PLS transmission model aiming to maximize the minimum radar echo gain,while constraining eavesdropper's signal-to-noise ratio and ensuring the quality-of-service for legitimate users.To solve this non-convex strongly-coupled multi-variable optimization problem,we propose an algorithm integrating alternating optimization,sequential rank-one constraint relaxation,and successive convex approximation to realize efficient solutions for subproblems.Simulation results demonstrate that compared with conventional fixed-antenna schemes,the proposed algorithm can enhance radar detection performance and significantly improve overall system performance,while guaranteeing communication security thresholds.关键词
