Les travaux présentés dans cette thèse portent sur un codeur appartenant à la même famille qu'un système de compression numérique appelé CELP, proposé en 1985 par B. A. Atal et al. Le principe du CELP repose sur une analyse par synthèse utilisant des techniques de prédiction linéaire, et sur une quantification vectorielle du signal d'excitation. Le débit de transmission atteint est inferieur à 10 kbps, pour une qualité sub-téléphonique du signal reconstruit, mais avec une complexité proche de 40 mips.

Abstract:
Cette thèse porte sur la conversion de format en codage de la parole (CELP), ou transcodage. La solution classique de conversion de format, appelée tandem, nécessite la mise en cascade d'une opération de décodage et d'une opération de re-codage. Cette approche par défaut utilisée aujourd'hui dans les réseaux de communications présente des inconvénients en terme de complexité, de délai et de qualité. Pour pallier ces problèmes, l'idée de transcodages dits « intelligents » a été étudiée. En s'appuyant sur les caractéristiques du modèle commun utilisé par les codeurs CELP, la conversion de format

Abstract:
As modern communications networks are heterogeneous and, therefore, highly variable, the design of source coders should reflect this network variability. It is desired that source coders are able to adapt instantly to any bit-rate constraint. Source coders that possess this property offer coding flexibility that facilitates optimal utilization of the available communication channel within a heterogeneous network. Flexible coders are able to utilize feedback information and therefore perform an instant re-optimization. This property implies that flexible audio coders are better suited for netwo
