A system and device communicates data. A modulation and mapping circuit modulates and maps data symbols into a plurality of multiple subcarriers that are orthogonal to each other based on a fixed or variable symbol rate. A frequency domain spreader circuit is operatively connected to the modulation and mapping circuit and spreads the multiple subcarriers over the frequency domain.
La présente invention concerne un système et un dispositif de communication de données. Un circuit de modulation et de mappage module et mappe des symboles de données en une pluralité de sous-proteuses multiples qui sont orthogonales les unes par rapport aux autres en se basant sur un débit de symboles fixe ou variable. Un circuit d'étalement de domaine de fréquence est connecté de manière opérationnelle au circuit de modulation et de mappage et il étale les sous-porteuses multiples sur le domaine de fréquence.
