Abstract
Disclosed herein is a demodulation method of a Layer-Division Multiplexing (LDM) system. The demodulation method may include receiving an LDM modulation signal, restoring a first-layer signal from the LDM modulation signal and remodulating the first-layer signal, restoring and remodulating a second-layer signal by performing cancellation of the amplitude component of the first-layer signal from the LDM modulation signal using signaling information independently of restoration and remodulation of the first-layer signal, and restoring a third-layer signal using the first-layer signal, the second-layer signal, and the LDM modulation signal.
