Abstract:
1. A method of processing a digital television (DTV) signal in a DTV receiver, the method comprising: estimating an impulse response of a channel through which the DTV signal is received; compensating channel distortion of the DTV signal using a coefficient bank; predicting noise of the compensated DTV signal that is amplified during the channel distortion compensation; and eliminating the predicted noise from the compensated DTV signal, wherein compensating channel distortion of the DTV signal comprises: initially setting an inverse of the estimated impulse response of the channel as a coefficient value of the coefficient bank; calculating an error between the compensated DTV signal and a decision value of the compensated DTV signal and continuously updating the coefficient value of the coefficient bank based on the calculated error; and compensating the channel distortion of the DTV signal using the updated coefficient value of the coefficient bank.
