STAR-RIS启用MU-MIMO ISAC系统可达和谈 secrecy rate
摘要
六代 (6G) 无线通信的各种新兴应用需求 seamless 集成通信与探测服务，推动集成探测通信 (ISAC) 系统的发展。使用统一波形为两种功能提供服务会引入额外的安全挑战，因为信令信号易受窃听。尽管文献中提出了多种针对单天线用户和窃听者的元 surface 启用 ISAC 系统的安全波束赋形方案，但针对多天线场景的最优方案仍未探索。本文填补了这一空白，研究了基于同时发射反射可重构智能 surface (STAR-RIS) 启用的数据流多用户多输入多输出 (MU-MIMO) ISAC 系统，提出一种最优波束赋形设计，以最大化系统的和保密率，同时确保多个目标的探测质量。 developed an alternating-optimization based iterative solution to tackle the non-convex optimization problem. The presented analysis confirms that the computational complexity of the proposed algorithm grows linearly with the number of metasurface elements. Our numerical results show the benefit of using STAR-RIS to increase the sum secrecy rate of the MU-MIMO ISAC system compared to its corresponding conventional RIS (cRIS)-enabled and w/o RIS systems.
