摘要： A receiving system and a method of processing broadcast signals in the receiving system are disclosed. The receiving system includes a tuner, a known sequence detector, a carrier recovery unit, a baseband processor, and a channel equalizer. The tuner receives a broadcast signal of a passband including a data group. Herein, the data group comprises mobile service data, a plurality of known data sequences, and signaling data. The known sequence detector estimates an initial frequency offset and detects a position of each known data sequence based on the known data sequence having the first data pattern. The carrier recovery unit acquires an initial frequency synchronization using the initial frequency offset estimated by the known sequence detector and estimates a residual frequency offset based upon the known data sequences having the second data pattern so as to perform carrier recovery. The baseband processor performs complex multiplication between the received broadcast signal and an output of the carrier recovery unit, thereby converting the passband broadcast signal to a baseband broadcast signal.

摘要： A receiving system and a method of processing data are disclosed herein. The receiving system includes a receiving unit, an equalizer, a block decoder, and an RS frame decoder. The receiving unit receives and demodulates a broadcast signal. Herein, the broadcast signal includes at least a mobile service data and a data group including a plurality of known data sequences. The equalizer channel-equalizes the data group included in the demodulated broadcast signal by using the plurality of the known data sequences. The block decoder performs turbo-decoding in block units on data of portion allocated to the channel equalized data group. And, the RS frame decoder configures an RS frame by gathering data of the turbo decoded M number of portions, wherein M is an integer greater than 1 (M>1). And, when a number of contiguous CRC errors is equal to (a maximum number of errors that can be corrected by RS erasure decoding)+1, wherein the number of contiguous CRC errors is determined by performing CRC decoding on each row of the RS frame, the RS frame decoder sets up erasure points in all data of the rows including the CRC errors, so as to perform RS erasure decoding on all columns of the RS frame in the column direction.

摘要： A receiving system and a method of processing data are disclosed herein. The receiving system a signal receiving unit, a known sequence detector, a first equalization unit, a second equalization unit, a block decoder, and an error correction unit. The signal receiving unit receives a broadcast signal including a data group multiplexed mobile service data with a plurality of known data sequences. The known sequence detector detects known data sequences from the broadcast signal. The first equalization unit updates an equalization coefficient by using the known data sequence during the known data section, thereby primarily channel-equalizing the known data sequence. The second equalization unit interpolates or extrapolates a converging equalization coefficient, thereby secondarily channel-equalizing the mobile service data, when the equalization coefficient converge. The block decoder performs turbo-decoding on the channel-equalized mobile service data in block units. And, the error correction unit performs error correction decoder on the decoded mobile service data, thereby correcting errors generated in the mobile service data.
