Fast Fourier Transform (FFT) inter frequency loss mitigation and Global Positioning System (GPS) receiver including it
Abstract:
Acquisition method for a localization receiver, in particular for a Global Positioning System (GPS) receiver. It involves the calculation of an interpolated Fast Fourier Transform (FFT) spectrum (S′) of correlated signals in which the frequency lines corresponding to half-integer values of the frequency resolution defined by the FFT are obtained by a combination of both amplitude and phase values of the FFT spectrum (S).
