Channel Customization for Limited Feedback in RIS-assisted FDD Systems
Weicong Chen, Chao-Kai Wen, Xiao Li +2
Reconfigurable intelligent surfaces (RISs) represent a pioneering technology to realize smart electromagnetic environments by reshaping the wireless channel. \textcolor[rgb]{0,0,0}…
Network-Assisted Full-Duplex Cell-Free Massive MIMO: Spectral and Energy Efficiencies
Mohammadali Mohammadi, Tung T. Vu, Hien Quoc Ngo +1
We consider network-assisted full-duplex (NAFD) cell-free massive multiple-input multiple-output (CF-mMIMO) systems, where full-duplex (FD) transmission is virtually realized via h…
Superdirective Arrays with Finite-Length Dipoles: Modeling and New Perspectives
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Dense arrays can facilitate the integration of multiple antennas into finite volumes. In addition to the compact size, sub-wavelength spacing enables superdirectivity for endfire o…
On the Performance of Zero-Forcing Processing in Multi-Way Massive MIMO Relay Networks
Chung Duc Ho, Hien Quoc Ngo, Michail Matthaiou +1
We consider a multi-way massive multiple-input multiple-output relay network with zero-forcing processing at the relay. By taking into account the time-division duplex protocol wit…
Multi-Way Massive MIMO with Maximum-Ratio Processing and Imperfect CSI
Chung Duc Ho, Hien Quoc Ngo, Michail Matthaiou +1
This paper considers a multi-way massive multiple-input multiple-output relaying system, where single-antenna users exchange their information-bearing signals with the help of one…
Multipair Two-way Half-Duplex Relaying with Massive Arrays and Imperfect CSI
Chuili Kong, Caijun Zhong, Michail Matthaiou +2
We consider a two-way half-duplex relaying system where multiple pairs of single antenna users exchange information assisted by a multi-antenna relay. Taking into account the pract…
