Enhanced channel estimation for near-field IRS-aided multi-user MIMO
system via deep residual network
In this paper, channel estimation (CE) of intelligent reflecting surface aided near-field (NF) multi-user communication is investigated. Initially, the least square (LS) estimator and minimum mean square error (MMSE) estimator for the estimated channel are designed, and their mean square errors (MSEs) are derived. Subsequently, to fully harness the potential …
