Abstract

In this paper the use of time-frequency representations for interference mitigation is discussed. In particular an excision algorithm is proposed and applied to the context of GNSS receivers. The algorithm is tested under different working conditions and its performances are assessed by means of the Receiver Operative Characteristics (ROC). The method is effective for interference removal and outperforms past algorithms already present in the literature.
