Abstract
(DE)
Eine Einrichtung zur Durchführung von Suchprozeduren umfaßt einenSpeicher zur Abspeicherung einer digitalen Empfangs-Datenfolge und einen Speicher, in welchem eine vorgegebene Korrelations-Datenfolge gespeichert ist. Eine Korrelatoreinrichtung umfaßt einen ersten Abschnitt (A1), in welchem Teilsequenzen der Empfangs-Datenfolge mit Teilsequenzen der Korrelations-Datenfolge korreliert werden. In dem zweiten Abschnitt (A2) wird eine einstellbare Anzahl K von Teilsequenz-Korrelationsergebnissen (OUT1) zu einem akkumulierten Korrelationsergebnis (OUT2) aufaddiert.
(EN)
The invention relates to a device for carrying out search procedures, comprising a memory for storing a digital receive data sequence and a memory in which a predetermined correlation data sequence is stored. A correlator device comprises a first section (A1) in which partial sequences of the receive data sequence are correlated with partial sequences of the correlation data sequence. In the second section (A2), an adjustable number (K) of partial sequence correlation results (OUT1) are added up to produce an accumulated correlation result (OUT2).
(FR)
L'invention concerne un dispositif destiné à la mise en oeuvre de procédures de recherche, composé d'une mémoire destinée à enregistrer une suite de données de réception numérique, et d'une mémoire contenant une suite de données de corrélation prédéfinie. Un dispositif de corrélation comporte une première section (A1) dans laquelle des séquences partielles de la suite de données de réception sont corrélées avec des séquences partielles de la suite de données de corrélation. Dans la deuxième section (A2), un nombre réglable K de résultats de corrélation de séquences partielles (OUT1) est additionné à un résultat de corrélation cumulatif (OUT2).
