Abstract

This research aims to optimize the MIMO communication system based on reconfigurable intelligent surfaces (RIS) in industrial environments. First, we construct a suitable channel model and propose an optimization problem to maximize the system’s received power. Subsequently, to address this challenge, we develop an alternating optimization strategy based on the gradient projection method (GPM) , which iteratively updates the RIS phase-shift matrix, transmit beamforming vector, and receive combining vector. We further study the influence of RIS deployment locations and compare their performance with the traditional decode-and-forward (DF) relay. Simulation results demonstrate that configuring the RIS with 18×18 elements achieve comparable performance to traditional DF relays. When increasing the RIS scale to 24×24, the received power improves by 172.7% compared to DF relay performance. These results provide valuable insights for optimizing the deployment and enhancing the performance of RIS-assisted communication systems in industrial scenarios.
