Title (EN) A MULTI-MODULATION TRANSMITTING METHOD
(FR) PROCEDE D'EMISSION MULTI-MODULATION
Abstract: front page image
(EN)A multi-modulation transmitting method which combines a plurality of independent sine waves into a composite wave which is a non-orthogonal multi-modulation symbol, wherein each of said independent sine waves is referred to as sub-wave, the amplitude, frequency and phase of said independent sine wave can be any value within the value range thereof, and each of said independent sine waves are non-orthogonal to each other; the composite wave is multi-point sampled; each sub-waves of said non-orthogonal multi­modulation symbol are decomposed in order to realize data communication. It can improve the frequency utilization and signal­noise ratio greatly, which can in turn increase the transmit rate greatly.
(FR)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.
