Confidence-Guided Adaptive Beam Selection for Vision-Aided Beam Tracking in mmWave Systems
Sohani Munteha Hiam, Mohammad Soleymani, Rafael F. Schaefer
Vision-aided beam tracking reduces mmWave beam-training overhead by predicting beam indices from camera observations. Fixed top- selection, however, assigns the same candidate b…
Quantization Limitations of Leakage Suppression in Self-Calibrating Monostatic Integrated Sensing and Communication MIMO Systems
Jan Adler, Florian Gast, Gerhard P. Fettweis +1
Power leaking directly from transmitting into receiving radio-frequency chains is a key challenge in the realization of monostatic sensing applications with multi-antenna communica…
Semantic Communication Through the Lens of Context-Dependent Channel Modeling
Javad Gholipour, Rafael F. Schaefer, Gerhard P. Fettweis
Semantic communication has emerged as a promising paradigm for next-generation networks, yet several fundamental challenges remain unresolved. Building on the probabilistic model o…
Semantic Communication: From Philosophical Conceptions Towards a Mathematical Framework
Javad Gholipour, Rafael F. Schaefer, Gerhard P. Fettweis
Semantic communication has emerged as a promising paradigm to address the challenges of next-generation communication networks. While some progress has been made in its conceptuali…
Leveraging Angle of Arrival Estimation against Impersonation Attacks in Physical Layer Authentication
Thuy M. Pham, Linda Senigagliesi, Marco Baldi +3
In this paper, we investigate the utilization of the angle of arrival (AoA) as a feature for robust physical layer authentication (PLA). While most of the existing approaches to PL…
Secret Key Generation Rates for Line of Sight Multipath Channels in the Presence of Eavesdroppers
Amitha Mayya, Arsenia Chorti, Rafael F. Schaefer +1
In this paper, the feasibility of implementing a lightweight key distribution scheme using physical layer security for secret key generation (SKG) is explored. Specifically, we foc…
