APPARATUS AND METHOD FOR TRANSRECEIVING BROADCAST SIGNALS

摘要

Disclosed is a broadcast signal transmitter. The broadcast signal transmitter, according to one embodiment of the present invention, comprises: an input-formatting module for formatting a baseband and outputting data of at least one piece of physical layer pipe (PLP); a BICM module for error correction-processing the PLP data; a framing and interleaving module for interleaving the PLP data and generating a signal frame; and a waveform-generating module for inserting a preamble into the signal frame and performing OFDM modulation to generate a broadcast signal.
