摘要: A multi-carrier data communications system and method having high spectral efficiency. The includes encoding input digital at selected phase angles of a plurality sinusoidal waveforms to create modulated waveforms. An output analog waveform is generated where the encoded communication signals corresponding representations performed so that adjacent ones are separated in frequency by less than 15 Hz any sideband included within power least 50 dB below signal associated with sideband.
