摘要:
An OFDM reception device includes: a first channel estimation unit for estimating a channel distortion by using a signal that is supplied from the reception unit and has a first time interval; a second channel estimation unit for estimating a channel distortion by using a signal that is supplied from the reception unit and has a second time interval shorter than the first time interval; a selection unit for selecting and outputting one of a signal from the first channel estimation unit and a signal from the second channel estimation unit, according to a control signal from the control unit; and a correction unit for correcting a reception signal supplied from the reception unit, according to the channel estimation signal from the selection unit. The control unit determines the control signal to be supplied to the selection unit, according a reception state of the reception unit.
