- Abstract
- A signal multiplexing device and method using layered division multiplexing are disclosed. The signal multiplexing device according to one embodiment of the present invention comprises: a combiner forcombining a core layer signal and an enhanced layer signal at different power levels so as to generate a multiplexed signal; a power normalizer for lowering power of the multiplexed signal to power corresponding to the core layer signal; a time interleaver performing interleaving to be applied to both the core layer signal and the enhanced layer signal so as to generate a time-interleaved signal;and a frame builder for generating a broadcast signal frame by using the time-interleaved signal and L1 signaling information.
