BROADCASTING SIGNAL TRANSMITTER/RECEIVER AND BROADCASTING SIGNAL TRANSMISSION/RECEPTION METHOD

摘要

A broadcasting signal transmission method, according to one embodiment of the present invention, comprises the following steps: FEC encoding and bit interleaving PLP data and signaling information; building a frame by cell mapping the PLP data and the signaling information; and OFDM modulating the PLP data and the signaling information, wherein the step of FEC encoding and bit interleaving includes the steps of MISO encoding first PLP data, MIMO encoding second PLP data, and MISO encoding the signaling information, and the step of building a frame includes the steps of cell mapping PLP data cells in pairs in a frequency domain and interleaving the PLP data cells in pairs in the frequency domain.
