- Abstract
- An apparatus and a method for transmitting a broadcast signal using a layered division multiplexing are disclosed. An apparatus for transmitting a broadcasting signal according to an embodiment of thepresent invention comprises: a combiner that generates a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; a power normalizer that lowers power of the multiplexed signal to a power corresponding to the core layer signal; a time interleaver that generates a time-interleaved signal by performing interleaving that is applied to both the corelayer signal and the enhanced layer signal; a frame builder that generates a frame of the broadcast signal using the time-interleaved signal; and an OFDM transmitter that generates a pilot signal shared by the core layer corresponding to the core layer signal and the enhanced layer corresponding to the enhanced layer signal.
