Title:
レイヤードディビジョンマルチプレキシングを利用した信号マルチプレキシング装置および信号マルチプレキシング方法
Document Type and Number:
Japanese Patent JP7064535
Kind Code:
B2
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.
