Abstract
According to an aspect of the present invention, there is provided a communication apparatus including: a synchronizer configured to perform synchronization processing according to a Doppler shift on a reception signal; and an equalizer configured to perform equalization processing on a reception signal on which the synchronization processing has been performed, in which the synchronizer includes a correlator configured to output a correlation between a reception signal and a known preamble sequence and a correlation between the reception signal and a known postamble sequence, a slide correlator configured to output a sliding correlation based on an output of the correlator, and a Doppler estimator configured to estimate a Doppler shift based on the sliding correlation of the slide correlator.
