SIGNAL MULTIPLEXING DEVICE AND SIGNAL MULTIPLEXING METHOD USING LAYERED DIVISION MULTIPLEXING.

摘要

Disclosed are a signal multiplexing device and method using layered division multiplexing. The signal multiplexing method, according to one embodiment of the present invention, comprises: a combiner for combining a core layer signal and an enhanced layer signal in power levels different from each other; and a time interleaver for performing interleaving which is applied to both the core layer signal and the enhanced layer signal.
