In an orthogonal code division multiple access (OCDMA) radio communication system having at least one base station and a plurality of remote subscriber terminals, the improvement comprising the method of reducing the sensitivity of OCDMA to access noise due to time base error and multipath delay spread comprising reducing the size of the orthogonal signal set on a single carrier (15), and providing additional carriers with orthogonal frequency spacing for additional subscriber capacity (12, 19).

L'invention porte sur une amélioration apportée à un système de radiocommunication à multiplexage par répartition de code orthogonal (OCDMA) comportant au moins une station de base et plusieurs terminaux d'abonnés à distance. L'amélioration consiste en un procédé permettant de réduire la sensibilité de l'OCDMA à un bruit de fond dont sont responsables une erreur de base de temps ainsi qu'un accroissement des retards de trajets multiples, procédé consistant à réduire la taille du jeu de signaux orthogonaux sur une porteuse unique (15) et à fournir des porteuses complémentaires pourvues d'un espacement orthogonal de fréquence aux fins d'un potentiel supplémentaire d'abonnés (12, 19).
