PROBLEM TO BE SOLVED: To attain acceleration of a blind equalization process for an adaptive equalizer including a plurality of taps, each having a corresponding coefficient, without reducing equalization quality. SOLUTION: The blind equalization process includes following steps. First of all, blind equalization (204) is performed on a subset of coefficients, less than all coefficients, in the adaptive equalizer. Then, it is judged whether the coefficients of the subset have converged or not and if the coefficients have converged (206), a decision directed adaptive equalization process (220) is initiated. If the coefficients have not converged, a larger subset of coefficients is used to repeat the step of performing the blind equalization (208, 212, 216). COPYRIGHT: (C)2008,JPO&INPIT
