基于统计CSI的RIS辅助通感一体化波束成形设计
Joint Beamforming Design for RIS-aided Integrated Sensing and Communication System with Statistical CSI
摘要
Abstract
With the development of wireless communication technology,Reconfigurable Intelligent Surface(RIS)and Integrated Sensing and Communication(ISAC)have attracted more and more attention.Aiming at the high cost of acquiring instantaneous channel state information in RIS-aided ISAC system,a joint beamforming design scheme based on statistical Channel State Information(CSI)is proposed.Firstly,the deterministic equivalent of the ergodic rate of the system is analyzed using statistical CSI.Then,by maximizing the deterministic equivalence under the perceived performance constraints,an alternate optimization algorithm is proposed to design the opti-mal base station transmission covariance matrix and RIS diagonal phase shift matrix.Finally,simulation results validate the effectiveness of the proposed scheme and reveal the tradeoff between communication and perceptual performance.关键词
