Abstract
A device and method of compensating for degradation of a received signal in a digital television receiver is disclosed. The device comprises a pre-distortion filter delaying and gain controlling a digital IF signal according to an input parameter control signal; a synchronizer for demodulating a baseband signal by using a pilot signal included in an output signal of the pre-distortion filter, and restoring timing; a channel equalizer for canceling multipath distortion occurring while a television signal passes a transmission channel; and a controller for outputting a parameter control signal such that a filter tap energy output from the channel equalizer becomes a maximum.
