Abstract

L’invention concerne un système pour transmettre des informations par un codec de la parole (dans la bande) tel qu’on le trouve dans un réseau de communication sans fil. Un modulateur transforme les données en un signal de type bruit spectral sur la base de la mise en correspondance d’une impulsion mise en forme à des positions prédéterminées dans une trame de modulation, et le signal est encodé efficacement par un codec de la parole. Une séquence de synchronisation, qui procure la synchronisation de trame de modulation au niveau du récepteur, est détectée sur la base de l’analyse d’un motif de crête de corrélation. Un protocole de demande/réponse procure un transfert fiable des données à l’aide d’une redondance des messages, d’une retransmission et/ou de modes de modulation robustes dépendant des conditions de canal de communication.
