Deep Learning For Super Resolution Channel Estimation In Reconfigurable Reconfigurable intelligent surface (ris) is a promising candidate technology for the upcoming sixth generation (6g) communication system for its ability to mani. We first model the channel estimation in sixth generation (6g) systems as a super resolution problem and adopt a deep residual attention approach to learn the nontrivial mapping from the received measurement to the reconfigurable intelligent surface (ris) channel.
Architecture Of Our Proposed Reconfigurable Intelligent Surface This study focuses on channel estimation for reconfigurable intelligent surface (ris) assisted mmwave systems, in which the ris is used to facilitate base to user data transfer. In this paper, we study the channel estimation problem for the ris aided multi user millimeter wave (mmwave) multi input multi output (mimo) system. In this work, a channel estimation scheme for the ris assisted wireless communication system is proposed, which is demonstrated to perform well in a time variant scenario. the cascaded ris channel is modeled as a state space model based upon the mobility situations. These methods aim to improve the accuracy and efficiency of channel estimation in ris‐assisted cell‐free systems while minimizing pilot overhead.
