摘　　要：针对非完美窃听信道状态信息(CSI)的情况,提出一种智能透射面(ITS)与智能反射面(IRS)联合辅助的多用户安全传输方案。首先,构造最大化系统加权和安全速率(WSSR)优化问题;其次,设计一个WSSR最大化鲁棒波束赋形算法,用以交替设计多用户功率分配因子、ITS波束赋形向量和IRS相位偏移向量;再次,为了综合评估该系统的安全性能与能量效率,构造系统安全能量效率(SEE)优化问题,并设计一个SEE最大化鲁棒波束赋形算法;最后,分析所提算法的收敛性和计算复杂度。仿真结果表明,所提算法具有较好的安全性和鲁棒性。Aiming at non-perfect eavesdropping channel state information(CSI),a joint-assisted multiuser 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 maximize 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 performance 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 convergence and computational complexity of the proposed algorithm are analyzed.Simulation results demonstrate that the proposed algorithms exhibit good security and robust performance.
