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.
