A Novel Doppler Rate Estimator Based on Fractional Fourier Transform for High-Dynamic GNSS Signal
When the fractional Fourier transform (FRFT) is introduced into the weak and high-dynamic global navigation satellite system (GNSS) signal acquisition, the 2-D search cell will be transferred to a 3-D one with respect to the code chip, the Doppler shift, and the Doppler rate. The proper determinatio...
