Abstract:
An apparatus and method for multiplexing signals using layered division multiplexing are disclosed. A signal multiplexing apparatus according to an embodiment of the present invention includes a combiner configured to combine a core layer signal and an enhanced layer signal at different power levels to generate a multiplexed signal, a power normalizer configured to reduce power of the multiplexed signal to power corresponding to the core layer signal, and a time interleaver configured to perform interleaving applied to both the core layer signal and the enhanced layer signal.

Claim (Index 9):
A signal demultiplexing method, comprising:\n performing time deinterleaving on a received signal corresponding to a broadcast signal frame; restoring, by a core layer BICM decoder, core layer data corresponding to the broadcast signal frame; extracting an enhanced layer signal by performing cancellation corresponding to the core layer data using the output from the core layer BICM decoder; and restoring, by an enhanced layer BICM decoder, enhanced layer data corresponding to the enhanced layer signal.
