A digital television (DTV) receiving system includes an information detector, a timing recovery unit, a carrier recovery unit, and a phase compensation unit. The information detector detects position information of a known data sequence periodically repeated in a DTV signal and estimates an initial frequency offset value. The timing recovery unit performs timing recovery on the DTV signal by detecting timing error information from the DTV signal using the position information. The carrier recovery unit performs carrier recovery on the DTV signal using the position information. The phase compensation unit compensates a phase offset of the DTV signal using the position information.
