Can I read GPS Interference Mitigation via RR-MSWF on EtoBox?

GPS Interference Mitigation via RR-MSWF by Roxana Birtum is a document available to read on EtoBox.

What is GPS Interference Mitigation via RR-MSWF about?

The document describes a method for mitigating interference for GPS receivers using cyclic spectral analysis and reduced-rank multistage Wiener filtering (RR-MSWF). It first obtains the cyclic frequencies of strong interference using cyclic spectral analysis of the received GPS signal. It then uses a blind adaptive frequency-shift filtering method based on the cyclic frequencies to separate the weak GPS signal from the interference. Finally, it implements the frequency-shift filtering using an efficient RR-
