What is it about?
In this work, we propose SORIS, a novel self-organized reconfigurable intelligent surface (RIS) hardware architecture that enables autonomous channel estimation and configuration without requiring dedicated links to the transmitter or receiver. By combining:
> a microcontroller-enabled RIS architecture,
> low-latency channel estimation using a small subset of transmitting RIS elements, and
> a low-complexity machine learning framework that exploits spatial channel correlation,
SORIS can efficiently acquire channel state information and dynamically reconfigure itself to assist wireless communications. We also provide a detailed complexity, wiring density, and control signaling analysis, and validate the feasibility and performance of the proposed design through Monte Carlo simulations.
