GNSS Jamming Interference: Characterization and Cancellation

Giulio Gabelli, Roberta Casile, Alessandro Guidotti, Giovanni E. Corazza

Abstract:	GNSS services provide cornerstone applications in all the fields of human activities: economical, social, and security. Thus, countermeasure to jamming signals, i.e., signals aiming at disrupting these services, play a crucial role. In this paper, we focus on the characterization and cancellation of jamming signals. In particular, we move from the techniques proposed in the literature, which suffer from high complexity or complex application to jamming signals due to their sparseness, and propose an efficient Interference Characterization and Cancellation (ICC) algorithm. The performance of the proposed algorithm is analyzed both in terms of probability of detection and residual after cancellation. Simulation results show that the proposed algorithm leads to large interfering signal suppression for all the analyzed cases. Moreover, a numerical complexity analysis is provided for the sake of completeness.
