智能透射面与智能反射面联合辅助的多用户安全传输方案
Multi-User Secure Transmission Scheme with Joint Assistance of IRS and ITS
摘要
Abstract
Aiming at non-perfect eavesdropping channel state information(CSI),a joint-assisted multi-user secure transmission scheme using intelligent transmissive surfaces(ITS)and intelligent reflective surfaces(IRS)is proposed.Firstly,an optimization problem is formulated to maximize the weighted sum secure rate(WSSR)of the system.Secondly,a robust beamforming algorithm is developed to maxi-mize the WSSR,which is used to alternately design the power allocation factors for multiple users,the ITS beamforming vector,and the IRS phase shift vector.Furthermore,to evaluate the security perfor-mance and energy efficiency of the system,a secure energy efficiency(SEE)optimization problem is constructed,and a robust beamforming algorithm is proposed to maximize the SEE.Finally,the conver-gence and computational complexity of the proposed algorithm are analyzed.Simulation results demon-strate that the proposed algorithms exhibit good security and robust performance.关键词
