Simulink-based Open-source Simulator for the Narrowband Interference Mitigation in E5A Galileo Band

One of the channel impairments that may affect the functionality of a GNSS receiver is the presence of narrowband interference, either intentional, from malicious third-party attacks or non-intentional, from other systems sharing the same frequency bands or from harmonics of other systems using nearby frequency bands. In this paper, we investigate three narrowband interference mitigation methods and compare them in terms of acquisition and tracking performance. The simulations are performed with an open-source Simulink simulator available in our group.
