Abstract

According to one embodiment of the present invention, an equalization method for an equalizer comprises: a step of calculating amplitudes of equalization signals corresponding to each of a plurality of equalization coefficients; and a step of selecting, as an equalization coefficient of the equalizer, the equalization coefficient from among the plurality of equalization coefficients that corresponds to the equalization signal having a predetermined amplitude.
