ABSTRACT:
A demodulator is constituted by: a clock recovery circuit for generating a recovered clock from the series of received data and outputting the recovered clock; a state estimation circuit for making an estimation about a reception state such as waveform distortion or the like from the series of received data, and outputting waveform information based on the result of the estimation; and a correlator for correcting a reference and/or sample points on the basis of the recovered clock and the waveform information, obtaining a correlation value between the series of received data and the reference from a plurality of the sample points, and outputting demodulated data on the basis of the correlation value.
