摘要

同时发射和反射可重构智能表面(STAR-RISs)最近被用于增强安全传输,因为它能够操纵全空间电磁信号。先前的工作主要是研究单一的STAR-RIS辅助保密通信系统,没有揭示合作的STAR-RIS链路的潜力。提出了一种包含多个合法用户(lu)和窃听者(eve)的双STAR-RIS增强安全通信网络。为保证公平性,通过对有源波束形成和无源T&R波束形成进行联合优化,提出了最小保密率最大化问题。针对高度非凸非线性优化问题,采用交替优化方法,提出了一种主动式和被动式波束形成优化算法。其中,设计了一种基于低复杂度序列约束松弛(SCR)的无源T&R波束形成优化算法。仿真结果表明,双星-RIS辅助网络的安全性能优于单星-RIS /双星-RIS /单星-RIS辅助网络。此外,与传统的基于可控硅的波束形成优化算法相比,该算法显著减少了计算时间(即资源分配时间)。

Double STAR-RIS Enhanced Secure Wireless Communications
Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) have recently been employed to enhance the secure transmission due to the ability to manipulate the full-space electromagnetic signals. Prior works mainly investigate the single STAR-RIS aided secure communication system, which does not reveal the potential of the cooperative inter-STAR-RIS link. In this paper, a double STAR-RIS enhanced secure communication network involving multiple legitimate users (LUs) and eavesdroppers (Eves) is proposed. For fairness, the minimum secrecy rate maximization problem is formulated by jointly optimizing the active beamforming and passive transmission and reflection (T&R) beamforming. To deal with the highly non-convex nonlinear optimization problem, an active and passive beamforming optimization algorithm is proposed by employing the alternating optimization method. Wherein, a low-complexity sequential constraint relaxation (SCR) based algorithm is designed to solve the passive T&R beamforming optimization problem. Simulation results demonstrate that the secure performance in the double STAR-RIS assisted system outperforms that in the single RIS/double RIS/single STAR-RIS aided network. Furthermore, the proposed algorithm significantly reduces computational time (i.e., resource allocation time) compared with the traditional SCR based beamforming optimization algorithm.
