Abstract:
1. A VSB reception system comprising: a demodulating part for receiving, convening, and demodulating a signal; a frequency domain equalizing part for equalizing the demodulated signal for removing a distorted component from the demodulated signal; and a noise removing pan for (a) receiving the equalized signal, (b) calculating a reference error signal that is a difference between the equalized signal and a signal having noise extracted therefrom (c) receiving the reference error signal and a noise signal extracted from the equalized signal at a first operator which calculates an error signal that is a difference between the reference error signal and the noise signal extracted from the equalized signal, (d) renewing parameters with reference to the reference error signal and the error signal, and (e) calculating a difference between the equalized signal and the extracted noise signal, to provide the signal having the noise extracted therefrom.
