    摘要: A method of transmitting a broadcast signal in a transmitter is provided. First data is encoded by adding parity data, and second data is encoded by adding parity data with different code rates, respectively. Signaling data is encoded. The encoded first data, the encoded second data, and the encoded signaling data are arranged in a frame among frames. The frames are modulated and transmitted. The frame among frames includes known data for channel estimation. The frames include a plurality of subframes that include a plurality of data units. The frame among frames includes the encoded first data unit and the encoded second data unit. The signaling data includes information for fast service acquisition which allows a receiver to locate upper layer signaling information. The signaling data further includes information on encoding type of data in a data unit, and information on a number of data units carried within a subframe.

    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.
