The present invention is to provide a digital radio receiver using a
carrier offset compensating circuit capable of compensating for carrier
offsets even in a TDD communication system, and extending the range that
can cope with offset frequencies to secure stable operation. The digital
radio receiver is such that an initial phase correction part determines a
phase shift from a known signal and corrects the phase shift, a
multiplication part performs multiplication of a tap coefficient of the
immediately preceding symbol from a first equalizer, and an equalizer
performs waveform equalization while updating the coefficient based on an
area-determination result.
