	| Abstract | In this paper, we propose deep learning scheme-based secure transmission in multiple intelligent reflecting surface (IRS) millimeter-wave system. The proposed scheme predicts active IRS and phase shift based on multi-task learning in deep neural network to maximize the secrecy rate. Simulation results based on 3D ray-tracing show that proposed scheme could predict the active IRS and phase shift with an accuracy exceeding 96%. In addition, the proposed scheme has a higher secrecy rate than the conventional single IRS and multiple IRS. |
