DIGITAL BROADCASTING TRANSMISSION/RECEPTION SYSTEM HAVING IMPROVED RECEIVING PERFORMANCE AND SIGNAL PROCESSING METHOD THEREOF

摘要

A digital broadcasting receiver and a method for processing a stream in a digital broadcasting receiver are provided. The receiver includes a demodulator for receiving and demodulating a transport stream (TS) including an additional data stream, an equalizer for equalizing the demodulated TS, and a turbo decoder for turbo-decoding the additional data stream in the equalized TS. The transport stream is generated by a digital broadcasting transmitter multiplexing the additional data stream, which is robustly processed by preprocessing data with a normal data stream. The turbo decoder includes a plurality of decoders for decoding the additional data stream and exchanging decoding reliability information with one another.
