Abstract: PURPOSE: A channel equalizer for an HDTV(high definition TV) is provided to increase convergence speed and improve efficiency in a multipath channel environment by equalizing the input signal size attenuation and phase distortion respectively. CONSTITUTION: A tap coefficient renewal module(40) renews the tap coefficient for equalizing the magnitude and phase of the signal. A storing module(70) stores the renewed signal magnitude and phase equalization tap coefficient and outputs them depending on the pilot signal location data. A linear interpolation module(80) interpolates the signal magnitude and phase equalization tap coefficient. A first and a second operation module(90,91) take sine and cosine functions for the phase-corrected signals. A complex processing module(120) generates a complex number by multiplying the corrected signal magnitude with the sine and cosine functions. A control module(130) provides the location data of the pilot signal to an equalizing module, the storing module(70), the tap coefficient renewal module(40) and the linear interpolation module(80).
