Abstract: A receiving system and a method of processing broadcast signal are disclosed herein. The receiving system includes N number of antennae, N number of demodulators, N number of known sequence detectors, and an equalizer. The N number of antennae each receives a broadcast signal including mobile service data and known data sequences. The N number of demodulators demodulates the broadcast signal received by the corresponding antenna. The N number of known sequence detectors detects known data sequences from the broadcast signal received by the corresponding antenna. The equalizer estimates a channel impulse response (CIR) of a broadcast signal received and demodulated by each antenna based upon each known data sequence detected by the N number of known sequence detectors, calculates an equalization coefficient of the broadcast signal received and demodulated by each antenna based upon at least one of the estimated CIRs, so as to compensate channel distortion of the broadcast signal received and demodulated by each antenna, and combines at least one or more distortion-compensated broadcast signal, thereby finally outputting the combined signal.

Abstract: A digital television receiving system includes a first known data detector, a second known data detector, and a selector. The first known data detector detects a location of a first known data sequence in a broadcast signal by calculating a first correlation value between the broadcast signal and a first reference known data sequence. Similarly, the second known data detector detects a location of a second known data sequence in the broadcast signal by calculating a second correlation value between the broadcast signal and a second reference known data sequence. The selector selects the location information detected by one of the first and second known data detectors with a greater correlation value.

Abstract: A digital television transmitter and a method of coding main and enhanced data in the digital television transmitter are disclosed. In the digital television transmitter, a byte-symbol converter converts main and enhanced data packets into symbols, wherein at least one of the enhanced data packets may include data place holders for known data symbols. A known data generator generates a known data symbol. A symbol processor processes a first symbol outputted from the byte-symbol converter. Herein, the symbol processor may post-decode a first bit of the known data symbol and output the post-decoded bit and an initialization data bit when the first symbol is a symbol representing one of the place holders. A trellis encoder has one or more memories for trellis-encoding a second symbol outputted from the symbol processor, wherein the memories are initialized when the initialization data bit is processed in the trellis encoder.

Abstract: A DTV receiver includes a tuner, a demodulator, a known sequence detector, and a frequency domain equalizer. The tuner initially receives a broadcast signal including valid data in which a known data sequence is periodically repeated. The demodulator demodulates the broadcast signal, and the known sequence detector detects the known data sequence from the demodulated signal. The frequency domain equalizer compensates channel distortion of the demodulated broadcast signal in a frequency domain using the detected known data sequence. In addition, the DTV receiver may further include a time domain equalizer which compensates channel distortion of the time domain signal, or a noise canceller which removes a predicted noise from the time domain signal.
