Abstract: A digital television (DTV) receiving system includes an information detector, a resampler, a timing recovery unit, and a carrier recovery unit. The information detector detects a known data sequence which is periodically inserted in a digital television (DTV) signal received from a DTV transmitting system. The resampler resamples the DTV signal at a predetermined resampling rate. The timing recovery unit performs timing recovery on the DTV signal by detecting a timing error from the resampled DTV signal using the detected known data sequence. The carrier recovery unit performs carrier recovery on the resampled DTV signal by estimating a frequency offset value of the resampled DTV signal using the detected known data sequence.

Abstract: A digital television (DTV) receiving system includes a tuner, a demodulator, a known data detector, an equalizer, a transmission detector, and a block decoder. The tuner receives a DTV signal having a data frame in which main and mobile service data are multiplexed. The demodulator demodulates the DTV signal, and the known data detector detects known data included in the mobile service data. The equalizer equalizes the demodulated DTV signal using the detected known data, and the transmission parameter detector detects an error correction mode from the equalized DTV signal. Finally, the block decoder decodes the equalized DTV signal for error correction using the detected error correction mode.
