Abstract: A broadcast signal transmission apparatus and method using layered division multiplexing are disclosed. A broadcast signal transmission apparatus according to an embodiment of the present invention includes a combiner configured to generate a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; a power normalizer configured to reduce the power of the multiplexed signal to a power level corresponding to the core layer signal; a time interleaver configured to generate a time-interleaved signal by performing interleaving that is applied to both the core layer signal and the enhanced layer signal; a frame builder configured to generate a broadcast signal frame using the time-interleaved signal; and an orthogonal frequency division multiplexing (OFDM) transmitter configured to generate a pilot signal that is shared by a core layer corresponding to the core layer signal and an enhanced layer corresponding to the enhanced layer signal.

Abstract: Disclosed herein are an apparatus and method for channel bonding-based multi-antenna signal transmission in a broadcasting system. An apparatus for channel bonding-based multi-antenna signal transmission includes an input formatting unit for converting input data into a Physical Layer Pipe (PLP), a stream partitioning unit for partitioning the PLP into pieces of data to be transmitted to two or more channels, respectively, and two or more transmission units for transmitting the pieces of data resulting from partitioning to corresponding channels through multiple antennas.
