Abstract

In wireless communication system, IRS can regulate the phase shift of reflecting units to reflect signals, which is used to enhance user signals and suppress eavesdropper signals and solve the problem of secure communication between base station and users. To address this issue, this paper proposed a secure communication scheme for multi IRS assisted multi user-multiple input single output system, with the goal of maximizing system weighted sum secrecy rate. This scheme firstly decomposed the problem of maximizing weighted sum security rate into two subproblems: transmission beamforming and artificial noise vector optimization, and multi-IRS phase matrix optimization. And then, this scheme transformed each subproblem into a simple convex subproblem for solution by using methods such as semidefinite relaxation, citation theorems, auxiliary variable substitution, and first-order Taylor approximation. Finally, this paper obtained the maximum weighted sum secrecy rate by sequentially solving two convex optimization subproblems based on the alternating optimization algorithm. The numerical simulation results show that the proposed algorithm scheme can effectively enhance the secure communication performance of the system compared with the other three schemes, and indicate that multiple IRS deployments can achieve better system security than a single IRS.
