Precision of channel estimation is improved. An OFDM reception apparatus
for receiving and demodulating an OFDM signal which transmits a pilot
signal, comprises a channel estimation section for calculating a channel
response before interpolation by performing computation between a
frequency-domain OFDM signal and the pilot signal, performing
interpolation with respect to the before-interpolation channel response
using a plurality of filters having different characteristics from each
other, and outputting a plurality of interpolated channel responses based
on respective results of the interpolation obtained by the plurality of
filters, an equalization section for performing waveform equalization
with respect to the frequency-domain OFDM signal based on the plurality
of interpolated channel responses, and outputting a plurality of
demodulated signals based on respective results of the waveform
equalization corresponding to the plurality of interpolated channel
responses, a determination section for determining one having best
quality from the plurality of demodulated signals, and outputting a
result of the determination, and a selection section for selecting and
outputting one of the plurality of demodulated signals in accordance with
the determination result.
