Abstract:
1. An enhanced VSB receiver for receiving and decoding a terrestrial broadcasting signal transmitted from a VSB transmitter, the enhanced VSB receiver comprising: a demodulator for receiving an input signal including main data and enhanced data from the VSB transmitter and converting the input signal into a base band signal; a data attribute generator for generating data attribute information indicating whether each symbol included in the input signal corresponds to the main data or the enhanced data; a slicer predictor for providing at least one of a slicer prediction signal and a prediction reliability signal by using the data attribute information generated from the data attribute generator; and a channel equalizer for correcting a distorted channel in the base band signal by using the slicer prediction signal, the prediction reliability signal, and the data attribute information, and outputting a channel equalizer output signal.
