Communication apparatus and communication method

Abstract

A communication apparatus including: a receiver to receive signals including reference signals at each of a plurality of different reception intervals; and a processor to estimate phase differences between the signals based on the reference signals, to determine a plurality of phase difference candidates for each of the reception intervals based on the phase differences, to select, from among a plurality of combinations of the phase difference candidates for the reception intervals, a combination of the phase difference candidates between the signals, and to estimate a frequency deviation of the signals based on the phase difference candidates included in the combination.
