摘要： 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.

摘要： 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.

摘要： A transmitting system, a receiving system, and a method of processing broadcast signals are disclosed. Herein, the transmitting system includes an RS frame encoder, a block processor, a group formatter, and a trellis encoding module. The RS frame encoder performs error correction encoding on an RS frame payload including mobile service data so as to form an RS frame, divides the RS frame into a plurality of portions, and outputs the divided RS frame portions. The block processor performs one of ½-rate encoding and ¼-rate encoding on each bit of the mobile service data included in each portion. The group formatter maps a portion including symbols of the ¼-rate encoded mobile service data and symbols of the ½-rate encoded mobile service data to a corresponding region of a data group. And, the trellis encoding module performs trellis encoding on the symbols of the ¼-rate encoded mobile service data and the symbols of the ½-rate encoded mobile service data of the data group.
