Abstract:
Embodiments of this disclosure provide a multicarrier modulation apparatus and method, a multicarrier demodulation apparatus and method and a system. In the embodiments of this disclosure, a new semi-orthogonal multicarrier waveform is designed for data modulation, odd-numbered subcarriers and even-numbered subcarriers of the waveform being respectively orthogonal to each other, but odd-numbered and even-numbered carriers being not orthogonal to each other, and sinusoid parts of the subcarriers being periodically reversed for a predefined number of times. In comparison with legacy orthogonal frequency division multiplexing (OFDM) multicarrier, the subcarrier spacing of such multicarrier is halved. Hence, the spectral efficiency is doubled, and as the sinusoid parts are reversed, the system performance is improved.

Claim (Index 3):
The apparatus according to  claim 2 , wherein odd-numbered subcarriers of the multiple subcarriers are orthogonal to each other, and even-numbered subcarriers of the multiple subcarriers are orthogonal to each other.
