DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA

摘要

A digital broadcast system and processing method that can transmit/receiv e digital broadcast signal are disclosed. More specifically, when a known da ta sequence is inputted to a trellis encoder, by having the transmitting sys tem initialize a memory within the trellis encoder and trellis -encode the i nputted data, thereby transmitted the processed data, and by having the rece iving system estimate known data information, which is to be used for freque ncy synchronization and channel equalization, the receiving performance of t he receiving system may be enhanced in a situation undergoing severe and fre quent channel changes.
