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)…
Intelligent Reflecting Surfaces at Terahertz Bands: Channel Modeling and Analysis
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
An intelligent reflecting surface (IRS) at terahertz (THz) bands is expected to have a massive number of reflecting elements to compensate for the severe propagation losses. Howeve…
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…
A Scheduling Policy for Downlink OFDMA in IEEE 802.11ax with Throughput Constraints
Konstantinos Dovelos, Boris Bellalta
In order to meet the ever-increasing demand for high throughput in WiFi networks, the IEEE 802.11ax (11ax) standard introduces orthogonal frequency division multiple access (OFDMA)…
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…
