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)…
Channel Estimation and Hybrid Combining for Wideband Terahertz Massive MIMO Systems
Konstantinos Dovelos, Michail Matthaiou, Hien Quoc Ngo +1
Terahertz (THz) communication is widely considered as a key enabler for future 6G wireless systems. However, THz links are subject to high propagation losses and inter-symbol inter…
Massive MIMO with Multi-Antenna Users under Jointly Correlated Ricean Fading
Konstantinos Dovelos, Michail Matthaiou, Hien Quoc Ngo +1
We study the uplink performance of massive multiple-input multiple-output (MIMO) when users are equipped with multiple antennas. To this end, we consider a generalized channel mode…
