(Non)-Coherent MU-MIMO Block Fading Channels with Finite Blocklength and Linear Processing
Junjuan Feng, Hien Quoc Ngo, Michail Matthaiou
This paper studies the coherent and non-coherent multiuser multiple-input multiple-output (MU-MIMO) uplink system in the finite blocklength regime. The i.i.d. Gaussian codebook is…
Mirror Prox Algorithm for Large-Scale Cell-Free Massive MIMO Uplink Power Control
Muhammad Farooq, Hien Quoc Ngo, Le-Nam Tran
We consider the problem of max-min fairness for uplink cell-free massive multiple-input multiple-output (MIMO) subject to per-user power constraints. The standard framework for sol…
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…
Superdirective Antenna Pairs for Energy-Efficient Terahertz Massive MIMO
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Terahertz (THz) communication is widely deemed the next frontier of wireless networks owing to the abundant spectrum resources in the THz band. Whilst THz signals suffer from sever…
Massive MIMO for Serving Federated Learning and Non-Federated Learning Users
Muhammad Farooq, Tung Thanh Vu, Hien Quoc Ngo +1
With its privacy preservation and communication efficiency, federated learning (FL) has emerged as a promising learning framework for beyond 5G wireless networks. It is anticipated…
Channel Estimation in RIS-assisted Downlink Massive MIMO: A Learning-Based Approach
Tung T. Vu, Trinh Van Chien, Canh T. Dinh +2
For downlink massive multiple-input multiple-output (MIMO) operating in time-division duplex protocol, users can decode the signals effectively by only utilizing the channel statis…
