Interference Mitigation in Tracking Loop of GPS Receiver based on Adaptive Filtering

Interference Mitigation in Tracking Loop of GPS Receiver based on Adaptive Filtering

Spoofing has vital role in distorting Global Positioning System (GPS) signals. In this paper, a plenary anti-spoofing approach based on adaptive filtering is proposed to diminish spoofing effects. The suggested method can be easily implemented in tracking loop of GPS receiver. An adaptive filter based on the least mean square has been developed for estimating the genuine parameters of counterfeit signal. As a primary step, the proposed technique is implemented in software receiver to prove the ...

Adaptive magnitude spectrum algorithm for Hilbert–Huang transform based frequency identification

Adaptive magnitude spectrum algorithm for Hilbert–Huang transform based frequency identification

An innovative Hilbert ndash;Huang transform (HHT) based frequency identification approach designated as adaptive magnitude spectrum algorithm(AMSA) is proposed in this paper. Characterized by the a posteriori property, the AMSA does not need the a priori information about the modalfrequencies to be identified, and the situations that a modal frequency may be contained along specific segments of the whole time duration ofone or more intrinsic mode functions (IMFs) are allowed for automatically ...
