An OFDM receiver apparatus mounted on a movable object for receiving an
OFDM signal, includes a plurality of directional antennas which receive
an OFDM signal, an estimator to estimate a center frequency of a spectrum
of a Doppler component from one of the received signals or a multiplexed
signal obtained by multiplexing the received signals, a shift quantity
calculator to calculate a shift quantity from the estimated center
frequency of the estimator and directivity information representing
directivity directions of the directional antennas, a plurality of
frequency shifters to subject the received signals to frequency shift
according to the shift quantity to compensate for Doppler shift, a
combining unit to diversity-combine frequency shifted signals of the
frequency shifters, and a demodulator/decoder to demodulate and decode
combining diversity signals of the combining unit.
