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.
