Channel Estimation for Double-RIS-Assisted MIMO Communication Systems Based on Deep Learning

This letter addresses the channel estimation (CE) problem in a double-reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) wireless communication system. Existing solutions often introduce additional control overhead due to frequent updates of RIS phases and amplitudes. To address thi...

Radiomap Blind Prediction under Incomplete Observation: Error Characterization and Correctable Propagation-Prior Learning

Under incomplete observation, a population-level theory of deterministic radiomap blind prediction is established that identifies the conditional mean as its optimal target and separates prediction error into reducible predictor approximation and irreducible uncertainty caused by missing physical information.
