Abstract

L'invention concerne un système de télécommunications à spectre étalé à empilement de porteuses (10), basé sur un étalement de domaine fréquentiel multipliant une représentation à domaine temporel d'un signal dans la bande de base par un ensemble de porteuses sinusoïdales complexes superposées ou empilées. Dans une forme d'exécution préférée (10), l'étalement excite les séries d'une transformation de Fourrier rapide (FFT). Ceci réduit considérablement la complexité informatique pour des grandeurs FFT de sortie modérées. Des topologies de réseaux point-multipoint et multipoint-multipoint (sans noeuds) sont possibles. Une méthode d'annulation de code est comprise pour la suppression d'interférence et l'accroissement de la séparation de signaux en exploitant la diversité spectrale des diverses sources (11). Le système de base (10) peut s'étendre de manière à inclure des méthodes d'annulation à réseaux d'antennes multi-éléments (26/18), également pour la suppression d'interférence et l'accroissement de la séparation de signaux, au moyen d'une séparation dans l'espace. De telles méthodes permettent que des systèmes directifs et rétro-directifs soient adaptés, ou puissent être adaptés, à un environnement radio. De tels systèmes sont compatibles avec des formats de modulation à largeur de bande sur demande et d'ordre supérieur et utilisent des algorithmes d'adaptation à désétaleur évolués (SINR maximum).
