Analysis of parameters for jamming separation in GPS signals using Independent Component Analysis

Abstract

The Global Positioning System (GPS) is a worldwide service and it is used as a reference for many other time, altitude, latitude and longitude based systems. Intentional jammers can degrade the reception of GPS signals, causing the receivers to fall out of sync. The technique employed in Independent Components Analysis (ICA) provides the ability to separate the interference (jamming). In this paper, we analyze the influence of ICA parameters in the convergence and effectiveness of the method when applied to separate the GPS signal from the jamming from the received signal.
