Abstract

Cette invention concerne un procédé d'émission multi-modulation qui combine une pluralité d'ondes sinusoïdales en une onde composite formant un système multi-modulation non orthogonal. Chacune des dites ondes sinusoïdales indépendantes est considérée comme une sous-onde dont l'amplitude, la fréquence et la phase peuvent avoir n'importe quelle valeur dans la plage de valeurs considérée, et qui sont non orthogonales les unes par rapport aux autres. L'onde composite fait l'objet d'un échantillonnage du système multi-modulation non orthogonal. Chaque sous-onde est décomposée en vue de la communication de données. Ce procédé permet d'améliorer l'utilisation des fréquences et du rapport signal-bruit, ce qui se traduit à son tour par une augmentation importante du débit d'émission.
