Constellation Design for Robust Interference Mitigation
Athanasios T. Papadopoulos, Thrassos K. Oikonomou, Dimitrios Tyrovolas +4
This paper investigates symbol detection for single-carrier communication systems operating in the presence of additive interference with Nakagami-m statistics. Such interference d…
Physical Layer Security with Artificial Noise in MIMO Pinching-Antenna Systems
Pigi P. Papanikolaou, Dimitrios Bozanis, Sotiris A. Tegos +3
As next-generation wireless networks emerge, security is becoming a critical performance metric. However, conventional multiple-input-multiple-output (MIMO) systems often suffer fr…
Constellation Design and Detection under Generalized Hardware Impairments
Thrassos K. Oikonomou, Dimitrios Tyrovolas, Sotiris A. Tegos +3
This paper presents a maximum-likelihood detection framework that jointly mitigates hardware (HW) impairments in both amplitude and phase. By modeling transceiver distortions as re…
Visual Hand Gesture Recognition with Deep Learning: A Comprehensive Review of Methods, Datasets, Challenges and Future Research Directions

The rapid evolution of deep learning (DL) models and the ever-increasing size of available datasets have raised the interest of the research community in the always-important field…
A Novel Hybrid Grey Wolf Differential Evolution Algorithm
Ioannis D. Bougas, Pavlos Doanis, Maria S. Papadopoulou +8
Grey wolf optimizer (GWO) is a nature-inspired stochastic meta-heuristic of the swarm intelligence field that mimics the hunting behavior of grey wolves. Differential evolution (DE…
Heterogeneous Resource Allocation with Multi-task Learning for Wireless Networks
Nikos A. Mitsiou, Pavlos S. Bouzinis, Panagiotis G. Sarigiannidis +1
The optimal solution to an optimization problem depends on the problem's objective function, constraints, and size. While deep neural networks (DNNs) have proven effective in solvi…
On the Design of Super Constellations
Thrassos K. Oikonomou, Dimitrios Tyrovolas, Sotiris A. Tegos +3
In the evolving landscape of sixth-generation (6G) wireless networks, which demand ultra high data rates, this study introduces the concept of super constellation communications. A…
Waveform Design for Over-the-Air Computing
Nikos G. Evgenidis, Nikos A. Mitsiou, Sotiris A. Tegos +4
In response to the increasing number of devices expected in next-generation networks, a shift to over-the-air (OTA) computing has been proposed. By leveraging the superposition of…
On the Performance of RIS-assisted Networks with HQAM
Thrassos K. Oikonomou, Dimitrios Tyrovolas, Sotiris A. Tegos +4
