Semi-Blind Channel Estimation for RIS-Assisted mmWave Systems Based on Diffusion Models

Channel estimation in reconfigurable intelligent surface (RIS)-assisted millimeter-wave (mmWave) systems is challenging due to the high-dimensional nature of cascaded channels. Existing semi-blind schemes mitigate pilot overhead by exploiting unknown data symbols. Nevertheless, these schemes often fail to fully leverag...
