Abstract: A ATSC compliant digital television (DTV) receiver including an image rejection filter, an interpolator, a numerically controlled oscillator (NCO), a matched filter unit, a frequency converter, and a DC remover. The image rejection filter removes (filters out) an unwanted image signal and an adjacent channel's interference signal from a first intermediate frequency (IF) signal sampled at a first sampling frequency. The interpolator resamples (at a second sampling frequency) a signal output from the image rejection filter and compensates for a predetermined symbol timing offset in response to a first control signal, thereby outputting a second IF signal. The NCO down converts the second IF signal and simultaneously compensates for a predetermined carrier offset in response to a second control signal, thereby outputting a first complex signal. The matched filter unit receives the first complex signal and filters the first complex signal, thereby outputting a second complex signal.
