Kalman filter based channel tracking for RIS-assisted multi-user networks

In this paper, we investigate channel estimation in a reconfigurable intelligent surface (RIS) assisted multi-user network while considering the mobility of users. Based on a time-varying channel model, we utilize the Kalman filter (KF) that is able to exploit temporal correlation to track cascaded...
