UAV辅助的非理想STAR-RIS认知NOMA物理层安全性能分析
Security Performance Analysis of UAV-assisted Non-ideal STAR-RIS Cognitive NOMA Physical Layer
摘要
Abstract
The advantages of unmanned aerial vehicle(UAV)in modern warfare have received increasing attention,and configuring it with simultaneous transmitting and reflecting-reconfigurable intelligent surface(STAR-RIS)can achieve spectrum and energy efficiency in wireless networks at a low cost.Therefore,the UAV-assisted STAR-RIS cognitive radio non-orthogonal multiple access(CR-NOMA)architecture is considered and for real communication scenarios in which non-ideal transmission factors in-phase and quadrature-phase imbalance(IQI)exists,the impact of artificial noise(AN)on the security performance of the physical layer of the system is investigated,approximate expressions for the outage probability and interception probability of cognitive users are derived,and also the interception performance of users under the AN scenario is compared with that of the non-artificial noise scenario.Simulation results show that the far user has about 0.15 lower outage probability than the near user at 15 dB for lower IQI levels,while the near user has about 0.9 lower outage probability than the far user at 25 dB for higher IQI levels;and the addition of AN is able to reduce the user̓s interception probability by about 0.3,which improves the system security performance.关键词
