Privacy-preserving Channel Estimation in Cell-free Hybrid Massive MIMO Systems
Jun Xu, Xiaodong Wang, Pengcheng Zhu +1
We consider a cell-free hybrid massive multiple-input multiple-output (MIMO) system with users and access points (APs), each with antennas and radio freque…
Joint Sparse Beamforming and Power Control for Large-scale DAS with Network-Assisted Full Duplex
Xinjiang Xia, Pengcheng Zhu, Jiamin Li +3
In this paper, we studied the joint sparse beamforming and power control for network-assisted full duplex (NAFD) in large-scale distributed antenna system (L-DAS), where the remote…
Power Minimization for Wireless Backhaul Based Ultra-Dense Cache-enabled C-RAN
Jun Xu, Pengcheng Zhu, Jiamin Li +1
This correspondence paper investigates joint design of small base station (SBS) clustering, multicast beamforming for access and backhaul links, as well as frequency allocation in…
Performance of Network-Assisted Full-Duplex for Cell-Free Massive MIMO
Dongming Wang, Menghan Wang, Pengcheng Zhu +3
Network assisted full-duplex (NAFD) is a spatial-division duplex technique for future wireless networks with cell-free massive multiple-input multiple-output (CF massive MIMO) netw…
Deep Learning Based Pilot Design for Multi-user Distributed Massive MIMO Systems
Jun Xu, Pengcheng Zhu, Jiamin Li +1
This letter proposes a deep learning based pilot design scheme to minimize the sum mean square error (MSE) of channel estimation for multi-user distributed massive multiple-input m…
