DIGITAL BROADCAST TRANSMITTER/RECEIVER AND METHOD OF PROCESSING DATA

摘要

The present invention relates to a digital broadcast system. More specifically, the present invention inserts known data known by the transmitter/receiver in a specific place (or position) of the data domain which enhanced data is transmitted and transmits the data. And the receiver may use the known data during the demodulating and equalizing process, thereby enhance a receiving performance in a frequent change in channel and which require protection (or resistance) against intense noise.
