Cell-Free Massive MIMO Meets OTFS Modulation
Mohammadali Mohammadi, Hien Quoc Ngo, Michail Matthaiou
We provide the first-ever performance evaluation of orthogonal time frequency space (OTFS) modulation in cell-free massive multiple-input multiple-output (MIMO) systems. To investi…
Smart Radio Environments
Gabriele Gradoni, Marco Di Renzo, Ana Diaz-Rubio +27
This Roadmap takes the reader on a journey through the research in electromagnetic wave propagation control via reconfigurable intelligent surfaces. Meta-surface modelling and desi…
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…
Electromagnetic Modeling of Holographic Intelligent Reflecting Surfaces at Terahertz Bands
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
Intelligent reflecting surface (IRS)-assisted wireless communication is widely deemed a key technology for 6G systems. The main challenge in deploying an IRS-aided terahertz (THz)…
How Does Cell-Free Massive MIMO Support Multiple Federated Learning Groups?
Tung T. Vu, Hien Quoc Ngo, Thomas L. Marzetta +1
Federated learning (FL) has been considered as a promising learning framework for future machine learning systems due to its privacy preservation and communication efficiency. In b…
3-D Deployment of UAV Swarm for Massive MIMO Communications
Ning Gao, Xiao Li, Shi Jin +1
We consider the uplink transmission between a multi-antenna ground station and an unmanned aerial vehicle (UAV) swarm. The UAVs are assumed as intelligent agents, which can explore…
