摘要： A DTV transmitter includes a pre-processor pre-processing enhanced data, a data formatter generating enhanced data packets including the pre-processed enhanced data, and a multiplexer multiplexing the enhanced data packets with main data packets. The transmitter further includes an RS encoder RS-coding the multiplexed packets by adding systematic RS parity data to each main data packet and by adding non-systematic RS parity place holders to each enhanced data packet, and a data interleaver interleaving the RS-coded packets.

摘要： A digital television transmitter and a method of coding main and enhanced data in the digital television transmitter are disclosed. In the digital television transmitter, a byte-symbol converter converts main and enhanced data packets into symbols, wherein at least one of the enhanced data packets may include data place holders for known data symbols. A known data generator generates a known data symbol. A symbol processor processes a first symbol outputted from the byte-symbol converter. Herein, the symbol processor may post-decode a first bit of the known data symbol and output the post-decoded bit and an initialization data bit when the first symbol is a symbol representing one of the place holders. A trellis encoder has one or more memories for trellis-encoding a second symbol outputted from the symbol processor, wherein the memories are initialized when the initialization data bit is processed in the trellis encoder.

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.
