    • 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.
    • 本文公开了接收系统和处理数据的方法。 接收系统,信号接收单元,已知序列检测器,第一均衡单元,第二均衡单元,块解码器和纠错单元。 信号接收单元接收包括具有多个已知数据序列的数据组多路复用移动业务数据的广播信号。 已知的序列检测器从广播信号中检测已知的数据序列。 第一均衡单元通过在已知数据段期间使用已知数据序列来更新均衡系数,由此主要对已知数据序列进行信道均衡。 第二均衡单元插值或外推收敛均衡系数,从而当均衡系数收敛时,二次对移动业务数据进行信道均衡。 块解码器以块为单位对信道均衡的移动业务数据进行turbo解码。 并且,纠错单元对解码的移动业务数据执行纠错解码器,从而校正在移动业务数据中产生的错误。
