Abstract

Un corrélateur analogique-numérique (10) utilise plusieurs circuits échantillonneurs-bloqueurs (16-0 à 16-(M-1)), afin de stocker directement des échantillons d'un signal analogique reçu. Des bits d'un modèle de corrélation sont décalés par étages dans un registre de décalage de modèle de corrélation (26). L'état des bits de modèle de corrélation provoque soit l'inversion soit la non-inversion de la valeur présente dans le circuit échantillonneur-bloqueur (16), lorsque cette valeur est additionnée avec d'autres signaux produits de façon similaire qui proviennent des circuits échantillonneurs-bloqueurs restants, de façon à former la somme de sortie de corrélation par le réseau (30). La sortie du réseau (30) atteint son sommet lorsque les bits du signal numérique du modèle de corrélation sont décalés dans le registre (26) par étapes alignées sur les circuits échantillonneurs-bloqueurs qui contiennent le code nécessaire imprimé numériquement. Dans le mode de réalisation préféré, un registre de décalage à masque (28) est utilisé pour invalider sélectivement certains des circuits échantillonneurs-bloqueurs et les empêcher ainsi d'affecter la somme de sorties de la corrélation. A cet effet, des bits de masque correspondant à la longueur du code imprimé numériquement sont décalés par le registre à masque (28) simultanément avec les bits du modèle de corrélation se trouvant dans le registre (26).
