Joint Robust Beamforming Design for IRS-assisted Physical Layer Key Generation Under Hardware Impairments
摘要
Abstract
This paper investigates an Intelligent Reflecting Surface(IRS)-assisted Physical-layer Key Generation(PKG)system under residual Transceiver Hardware Impairments(THI).A closed-form expression for the Key Generation Rate(KGR)is derived,and a KGR maximization problem is formulated under the base station transmit power constraint and the unit-modulus constraint on the IRS phase shifts.To solve this problem,a robust optimization algorithm is proposed,which integrates Alternating Optimization(AO),Suc-cessive Convex Approximation(SCA),Semi-Definite Relaxation(SDR),and penalty methods to iteratively optimize the transmit beam-forming and IRS phase shifts.Numerical simulation results demonstrate that the proposed robust algorithm can effectively mitigate the impact of hardware impairments and improve the KGR.关键词
