Deep Reinforcement Learning Orchestration of Game-Theoretic User Association and Resource Allocation in HetNets
Sotiris Kopsinos, Alexandros I. Papadopoulos, Antonios Lalas +2
Managing dynamic User Association and Resource Allocation (UARA) in modern Heterogeneous Cellular Networks (HetNets) remains a critical open challenge. Existing mathematical optimi…
Geometry-Informed Optimization of Binary RIS Configurations for Communication and Sensing
Angelos Gkekas, Alexandros I. Papadopoulos, Petros Andreas Pantazopoulos +3
Practical Reconfigurable Intelligent Surfaces (RISs) often support only a small number of phase states, making their configuration inherently discrete. For a 1-bit RIS with ele…
Physics-Aware RIS Codebook Compilation for Near-Field Beam Focusing under Mutual Coupling and Specular Reflections
Alexandros I. Papadopoulos, Maria Anna Pistela, Dimitrios Tyrovolas +5
Next-generation wireless networks are envisioned to achieve reliable, low-latency connectivity within environments characterized by strong multipath and severe channel variability.…
A holistic perception system of internal and external monitoring for ground autonomous vehicles: AutoTRUST paradigm
Alexandros Gkillas, Christos Anagnostopoulos, Nikos Piperigkos +16
This paper introduces a holistic perception system for internal and external monitoring of autonomous vehicles, with the aim of demonstrating a novel AI-leveraged self-adaptive fra…
Multi-Sensor Fusion for UAV Classification Based on Feature Maps of Image and Radar Data
Nikos Sakellariou, Antonios Lalas, Konstantinos Votis +1
The cost, flexibility, and efficiency of modern UAVs make them attractive across many applications, but their proliferation has driven a rising number of malicious or accidental in…
An Open Platform for Simulating the Physical Layer of 6G Communication Systems with Multiple Intelligent Surfaces
Alexandros Papadopoulos, Antonios Lalas, Konstantinos Votis +4
Reconfigurable Intelligent Surfaces (RIS) constitute a promising technology that could fulfill the extreme performance and capacity needs of the upcoming 6G wireless networks, by o…
