Patent ID: 7312833

Claim:
A channel equalizing apparatus for a digital television receiver for performing channel equalization using equalizing algorithms, the apparatus comprising: a channel equalizing section for compensating for channel distortion using a blind algorithm and a decision directed algorithm among the equalizing algorithms; and a equalizing control section for calculating error values for compensating for the channel distortion from the blind algorithm and the decision directed algorithm and controlling the channel equalizing section to compensate for the channel distortion according to the calculated error values; the equalizing control section including, a decision directed error calculating section for calculating a decision directed error value, a Godard error calculating section for calculating a Godard error value, and a final error calculating section for calculating a final error value for compensating for the channel distortion using the decision directed error value and the Godard error value; and wherein the decision directed error value is calculated through steps of: generating a decision signal from an output of the channel equalizing section; and calculating a difference value between a phase of the decision signal and an output phase of the channel equalizing section.
