基于IRS的无人机安全通信联合优化技术研究
Research on IRS-based joint optimization technology of UAV security communication
摘要
Abstract
Because the intelligent reflecting surface(IRS)has the characteristics of passivity property,low power consumption and intelligent control,its development has brought new ideas to the physical layer security of UAS(unmanned aircraft system).Because the IRS can change the phase of the incident signals,fine-grained beamforming can be realized.As the IRS is a kind of hardware,its phase adjustment is uncontinuous.In view of the above,a joint optimization beamforming and phase adjustment scheme of UAV communication system with eavesdropping node is studied.By the IRS deployed on the relay UAV(unmanned aerial vehicle),the signals are reflected to the legal UAV as much as possible,while the illegal UAV receives less signals,so as to improve the security rate of the system.In this paper,the security rate obtained by different relay systems and the consumed system power under the condition of the same security rate are contrasted.The simulation results show that the system with IRS as relay node can improve the system security rate effectively and reduce the system power consumption.关键词
