Sparse Channel Estimation for SIM-based mmWave Near-Field Communications
Jiancheng An, Enyu Shi, Jiayi Zhang +4
In this paper, we address the channel estimation (CE) problem in SIM-based multi-user (MU) millimeter-wave (mmWave) near-field communication systems. To address the severe path los…

Improving Sum-Rate of Cell-Free Massive MIMO with Expanded Compute-and-Forward
Jiayi Zhang, Jing Zhang, Derrick Wing Kwan Ng +2
Cell-free massive multiple-input multiple-output (MIMO) employs a large number of distributed access points (APs) to serve a small number of user equipments (UEs) via the same time…
