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…

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…
