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 channel equalizer includes a first transformer, an estimator, an average calculator, a second transformer, a coefficient calculator, a compensator, and a third transformer. The first transformer converts normal data into frequency domain data, where a known data sequence is periodically repeated in the normal data. The estimator estimates channel impulse responses (CIR) during known data intervals adjacent to each normal data block. The average calculator calculates an average value of the CIRs. The second transformer converts the average value into frequency domain data. The coefficient calculator calculates equalization coefficients using the average value, and the compensator compensates channel distortion of each normal data block using the coefficients. The third transformer converts the compensated data block into time domain data.

摘要： A method of processing a digital broadcast signal includes Reed-Solomon (RS) encoding enhanced service data for each column of at least one RS frame payload and adding a Cyclic Redundancy Check (CRC) checksum byte at a right end of each row of the at least one RS frame payload to build at least one RS frame and forming data groups including the enhanced service data in the built RS frame and a plurality of known data sequences. Forming the data groups includes mapping the RS encoded enhanced service data into each of the data groups and inserting a place holder for a non-systematic RS parity into each of the data groups. The method further includes deinterleaving data in each of the data groups including the enhanced service data and the place holder and multiplexing the enhanced service data in each of the formed data groups with main service data.
