Supervised Learning Based Sparse Channel Estimation For RIS Aided Communications
ICASSP 2022accepted
An reconfigurable intelligent surface (RIS) can be used to establish line-of-sight (LoS) communication when the direct path is compromised, which is a common occurrence in a millimeter wave (mmWave) network. In this paper, we focus on the uplink channel estimation of a such network. We formu-late th…
