Two-level structured Bayesian sparse recovery for cascaded uplink channel estimation in RIS-assisted mmWave MIMO systems

Accurate and efficient channel estimation remains a major challenge in reconfigurable intelligent surface (RIS)-assisted multi-user millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems, especially under limited pilot resources and low signal-to-noise ratio (SNR) conditions. This paper proposes two nov...
