EnglishThe research work described in this paper is focused on the topic of the Radio Frequency Interference (RFI) mitigation techniques in the field of the Global Navigation Satellite Systems (GNSS). The paper focuses on an innovative interference mitiga-tion algorithm based on the Wavelet Transform. The first part of this paper provides a description of the Wavelet decomposition method and its use in the GNSS field. All the steps of the detection and mitigation algorithms exploiting this mathematical tool are described as well as its application on narrow-band interference mitigation. The proposed method exploits the compact time-frequency behavior of Wavelet functions; they allow for a good indentification of the interfering source and a synthetic reconstruction of the signal that can then be used for mitigation purposes. Simulation results showing the benefits of this Wavelet based mitigation technique on the acquisition and tracking stage in L1 GPS band, are presented.

| Abstract: | The research work described in this paper is focused on the topic of the Radio Frequency Interfer...ence (RFI) mitigation techniques in the field of the Global Navigation Satellite Systems (GNSS). The paper focuses on an innovative interference mitiga-tion algorithm based on the Wavelet Transform. The first part of this paper provides a description of the Wavelet decomposition method and its use in the GNSS field. All the steps of the detection and mitigation algorithms exploiting this mathematical tool are described as well as its application on narrow-band interference mitigation. The proposed method exploits the compact time-frequency behavior of Wavelet functions; they allow for a good indentification of the interfering source and a synthetic reconstruction of the signal that can then be used for mitigation purposes. Simulation results showing the benefits of this Wavelet based mitigation technique on the acquisition and tracking stage in L1 GPS band, are presented. | |
