DEVICE AND METHOD FOR RECEIVING DIGITAL BROADCAST SIGNAL

摘要

A broadcast signal transmitter is disclosed. The broadcast signal transmitter according to the present invention comprises: an input formatting module for de-multiplexing an input stream into at least one physical layer pipe (PLP); a BICM module for performing error-correction processing on data of the at least one PLP; a frame building module for generating a signal frame including the at least one PLP; and a waveform generation module for generating a broadcast signal by inserting a preamble into the signal frame and performing an OFDM modulation, wherein the waveform generation module comprises a pilot insertion module for inserting continual pilots (CPs) and scattered pilots (SPs) into the broadcast signal.
