Enhanced channel estimation for near-field IRS-aided multi-user MIMO system via a large deep residual network
Yan Wang, Yongqiang Li, Minghao Chen +3
In this paper, the channel estimation (CE) of intelligent reflecting surface-aided near-field (NF) multi-user communication is investigated. Initially, the least square (LS) estima…

Multi-stream Transmission for Directional Modulation Network via Distributed Multi-UAV-aided Multi-active-IRS
Ke Yang, Rongen Dong, Wei Gao +5
Active intelligent reflecting surface (IRS) is a revolutionary technique for the future 6G networks. The conventional far-field single-IRS-aided directional modulation(DM) networks…
