Two-Stage Channel Parameters and Covariance Estimation for RIS-Aided MIMO With Angular Dispersion

In this study, we propose a cascaded channel covariance matrix (C-CCM) estimation framework for millimeter-wave (mmWave) reconfigurable intelligent surface (RIS)-aided multiple-input multiple-output (MIMO) systems that explicitly accounts for the angular spread (angular dispersion) effect. We derive analytical expressi...
