The present invention relates to a channel equalizer for an HDTV capable of increasing a convergence rate for performing channel equalization on a ghost having a small size after performing channel equalization on a ghost having a size close to that of a distant ghost, . The channel equalizer of the present invention has an input signal Vn from the outside, a filter coefficient for a near ghost and a filter coefficient Cn1 + 1), And the filter coefficient Cn0 + 1) (Cn1 + 1), The input signal Vn) To obtain an output signal In, An FIR filter 21 for outputting an output signal I (i) of the FIR filter 21,nAnd a training sequence signal Ir) To obtain an error value. Based on this error value, a filter coefficient Cn0 + 1And outputs the result to the FIR filter 21.
