Abstract

L'invention concerne des systèmes, un appareil et des procédés de communication à multiplexage par code (100), des codeurs étant destinés à coder et à décoder des flux de données au moyen de codes synchrones sensiblement orthogonaux. Ces systèmes de communication à multiplexage par code (100) sont conçus pour coder des signaux de données à l'aide de codes qui permettent de maintenir à un niveau acceptable des artefacts de décodage, par exemple une diaphonie susceptible d'apparaître au cours d'une extraction de données ou à intervalles de temps pendant cette extraction. Certains systèmes s'appuient sur l'utilisation de codes orthogonaux synchrones produits par des vecteurs orthogonaux complexes. Dans un exemple, un code à phase temporelle à trois niveaux qui comporte neuf éléments de code et permet de coder et de décoder de signaux de données est un système de communication à sept voies.
