Abstract :
Recent years, the GNSS has a diverse and wide application field. It provides the services that using the personal location information. But, for the some people, it is undesirable service. Therefore, these people start using the Personal Privacy Devices. A study about the impact of PPDs and effective countermeasure to PPDs are required. In this paper, we analyze the effect on the anti-jamming technique by the PPD jammer. And we show the effect of frequency swept jammer is removed by applying reduced-rank approach. We also analyzed the performance of reduced-rank approach.
