ML-enabled RIS configuration with domain knowledge for improved performance and scalability.
摘要
This article introduces RISnet, a neural network architecture for optimizing reconfigurable intelligent surfaces (RIS) with mutual coupling and partial CSI. It addresses challenges like scalability, channel estimation, and joint optimization of precoding and RIS configuration. The work combines machine learning and domain knowledge for improved wireless communication performance.
