ABSTRACT:
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.
