Title:
BROADCASTING SIGNAL TRANSMITTER/RECEIVER AND BROADCASTING SIGNAL TRANSMISSION/RECEPTION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/105745
Kind Code:
A3
Abstract:
Disclosed is a broadcasting signal transmitter. A broadcasting signal transmitter, according to one embodiment of the present invention, comprises: a BICM encoder, which FEC encodes and bit interleaves PLP data and signaling information; a frame builder, which cell-maps the PLP data and signaling information, and builds a frame; a MISO encoder, which MISO encodes the PLP data for MISO transmission included in the PLP data and signaling information; and an OFDM generator, which OFDM modulates said PLP data and said signaling information, wherein the BICM encoder includes a MIMO encoder, which MIMO encodes the PLP data for MIMO transmission included in the PLP data, and the OFDM generator includes an additional preamble symbol insertion module, which inserts an additional preamble symbol into said frame.
