- Abstract
- A signal multiplexing apparatus using layered division multiplexing and a signal multiplexing method are disclosed. A signal multiplexing method according to one embodiment of the present invention comprises: a combiner for generating a multiplexed signal by combining a core layer signal and an enhanced layer signal at different power levels; a power normalizer for lowering the power level of themultiplexed signal to a power level corresponding to the power level of the core layer signal; and a time interleaver for performing interleaving applied to both the core layer signal and the enhancedlayer signal.
