(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…
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…
Virtually Full-duplex Cell-Free Massive MIMO with Access Point Mode Assignment
Mohammadali Mohammadi, Tung T. Vu, Behnaz Naderi Beni +2
We consider a cell-free massive multiple-input multiple-output (MIMO) network utilizing a virtually full-duplex (vFD) mode, where access points (APs) with a downlink (DL) mode and…
Data Size-Aware Downlink Massive MIMO: A Session-Based Approach
Tung T. Vu, Hien Quoc Ngo, Minh N. Dao +2
This letter considers the development of transmission strategies for the downlink of massive multiple-input multiple-output networks, with the objective of minimizing the completio…
When Cell-Free Massive MIMO Meets OTFS Modulation: The Downlink Case
Mohammadali Mohammadi, Hien Quoc Ngo, Michail Matthaiou
We provide a performance evaluation of orthogonal time frequency space (OTFS) modulation in cell-free massive MIMO (multiple-input multiple-output) systems. By leveraging the inher…
Intelligent Reflecting Surface-Aided Wideband THz Communications: Modeling and Analysis
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
In this paper, we study the performance of wideband terahertz (THz) communications assisted by an intelligent reflecting surface (IRS). Specifically, we first introduce a generaliz…
