Lightweight Pilot Estimation on LEO Satellite Signals for Enhanced SOP Navigation
Francesco Zanirato, Alessio Curzio, Francesco Ardizzon +5
The computation of positioning, navigation and timing (PNT) via signal of opportunity (SOP), where signals originally transmitted for communication, such as 5G, Wi-Fi, or DVB-S, ar…
Challenge-Response to Authenticate Drone Communications: A Game Theoretic Approach
Mattia Piana, Francesco Ardizzon, Stefano Tomasin
As drones are increasingly used in various civilian applications, the security of drone communications is a growing concern. In this context, we propose novel strategies for challe…
Authentication by Location Tracking in Underwater Acoustic Networks
Gianmaria Ventura, Francesco Ardizzon, Stefano Tomasin
Physical layer message authentication in underwater acoustic networks (UWANs) leverages the characteristics of the underwater acoustic channel (UWAC) as a fingerprint of the transm…
Detecting 5G Narrowband Jammers with CNN, k-nearest Neighbors, and Support Vector Machines
Matteo Varotto, Florian Heinrichs, Timo Schuerg +2
5G cellular networks are particularly vulnerable against narrowband jammers that target specific control sub-channels in the radio signal. One mitigation approach is to detect such…
Performance Limits for Signals of Opportunity-Based Navigation
Francesco Zanirato, Francesco Ardizzon, Laura Crosara +4
This paper investigates the potential of non-terrestrial and terrestrial signals of opportunity (SOOP) for navigation applications. Non-terrestrial SOOP analysis employs modified C…
Detecting 5G Signal Jammers Using Spectrograms with Supervised and Unsupervised Learning
Matteo Varotto, Stefan Valentin, Stefano Tomasin
Cellular networks are potential targets of jamming attacks to disrupt wireless communications. Since the fifth generation (5G) of cellular networks enables mission-critical applica…
