Abstract

Recently, intelligent reflecting surfaces (IRSs) have seen an upsurge of interest due to their ability to make the wireless environment programmable, which has historically been treated as an uncontrollable natural phenomenon. Even passive IRSs consisting of many reflecting units can autonomously adjust the reflection coefficients to alter the phase and amplitude of the incident signals. However, optimal reflection design for large IRSs are deemed to be impractical due to the underlying computational complexity. In this paper, we design IRS-assisted programmable wireless environment for secure communication using deep learning techniques. More specifically, we consider the k-nearest neighbor learning algorithm for significantly reducing the computational complexity in IRS design. Simulation results demonstrate the effectiveness of the proposed deep learning-based solutions as compared with traditional alternating optimization.
