ABSTRACT:
Disclosed is a method for estimating a Doppler frequency with phase information, thereby estimating a maximum Doppler frequency. The method for estimating the Doppler frequency includes the steps of measuring phases of phase samples from a plurality of slots of a received signal, evaluating a phase difference of the measured phase, and estimating a maximum Doppler frequency according to a mean of at least one phase difference.
