Abstract

The present invention provides a frequency estimation method for signal carrier. The method includes: determining a rough estimating value of frequency of a signal carrier at a receiving end; selecting a section of frequency spectrum sequence in the signal frequency spectrum within pass-band range in which the rough estimating value is a center value; obtaining a frequency spectrum sequence that is in conjugate symmetry with the section of frequency spectrum sequence by performing a sliding correlation operation to the section of frequency spectrum sequence and the frequency spectrum of the signal; calculating an exact estimating value of the frequency corresponding to the symmetry center by using two sections of frequency spectrum sequences that are in conjugate symmetry, thereby obtaining an exact estimating value of the carrier frequency of the signal. The present invention also provides a phase estimation method for signal carrier and a frequency estimation apparatus for signal carrier. The present invention enables flexible estimation of frequency and phase of a signal carrier according to corresponding precision requirement.
