[en] Both the jammer and the eavesdropper pose severe
threat to wireless communications due to the broadcast nature of wireless channels. In this paper, an intelligent reflecting surface (IRS) assisted secure communication system is considered, where a base station (BS) wishes to reliably convey information to a user, in the presence of both a jammer and an eavesdropper whose channel state information (CSI) is not perfectly known. Specifically, we aim to maximize the system achievable rate by jointly designing the BS’s transmit beamforming and the IRS’s reflect beamforming with imperfect CSI, while limiting the information leakage to the potential eavesdropper. Due to the non-convexity and intractability of the original problem induced by the CSI uncertainty, we utilize the auxiliary variables and General Sign-Definiteness transformation to convert the original optimization problem into a tractable convex optimization problem, and then obtain the high-quality optimal solution by using the successive convex approximation and penalty convex concave procedure. Numerical simulations demonstrate the superiority of our proposed optimization algorithm compared with existing approaches, and also reveal the impact of key parameters on the achievable system performance. | |
