摘要： Channel Equalization of a digital TV is disclosed. In channel equalization for restoring an original signal from a digital TV reception signal having passed through a channel, the present invention includes estimating an impulse response of the channel from a received signal having passed through the channel using conjugate-gradient algorithm, finding an equalizer coefficient in a frequency domain using the estimated impulse response of the channel, outputting a signal equalized by multiplying a signal resulting from transforming the received signal into the frequency domain by the found equalizer coefficient, and predicting to remove an amplified noise of the equalized signal using the conjugate-gradient algorithm in a time domain. Accordingly, the variation of the channel impulse response according to time can be tracked in the dynamic channel having fast channel variation as well as the static channel, whereby equalizing performance can be enhanced.

摘要： An enhanced VSB receiver includes a tuner which tunes an RF signal and converts it into an IF signal, an IF mixer which converts the IF signal into a baseband signal, and a demodulator which demodulates the baseband signal signal into a VSB signal. The enhanced VSB receiver further includes a map recovery unit which recovers VSB map information of the VSB signal, an enhanced equalizer for compensating channel distortion of the VSB signal and outputting an equalized symbol, and an enhanced Viterbit decoder for estimating whether polarity inversion occurred during a symbol period of the equalized symbol and Viterbi-decoding the equalized symbol based on the polarity estimation.
