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 9):
The apparatus according to  claim 4 , wherein the equalizing unit performs linear equalization on the demodulated data to which the subcarriers correspond by using a least mean square algorithm to obtain the demodulated data with no inter-subcarrier-interference as below:\n {circumflex over (x)} =( R H \u00b7R+\u03c3 2 \u00b7R ) \u22121 \u00b7R H \u00b7x\u2032;  where, R is a subcarrier correlation matrix, which is a full rank matrix, R H  is a conjugate transpose of the subcarrier correlation matrix, \u03c3 2  is white noise power, and x\u2032 is a vector of the demodulated data to which the subcarriers correspond.
