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
Konstantinos Foteinos, Manousos Linardakis, Panagiotis Radoglou-Grammatikis +4
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…
