有源智能反射面辅助的多用户安全通信优化设计
Secure Multi-User Communication Optimization with Active Reconfigurable Intelligent Surfaces
摘要
Abstract
Active reconfigurable intelligent surfaces can effectively mitigate the"dual fading"effect,significantly enhancing the reliability of signal transmission.However,the inherent broadcasting and openness of wireless channels introduce a prominent risk of confidential information leakage in such systems.To address this,an optimization problem is proposed with the goal of maximizing the total secure rate for multiple users.Due to the non-convex nature of this optimization problem,an alternating optimization algorithm is employed for global solution.Subproblems are solved using the simulated annealing algorithm and semi-definite relaxation algorithm.Simulation results show that the proposed scheme achieves significant improvements in security compared to existing solutions.关键词
