On Runlength Limited Codes for BICM Systems
Stephan Zeitz, Florian Roth, Meik Dörpinghaus +1
We study the use of runlength-limited (RLL) block codes in bit-interleaved coded modulation (BICM) systems. In this setting, the RLL code acts as the symbol mapper, whose assignmen…
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…
