Abstract

Ένας συντελεστής γραμμικής πρόβλεψης ενός σήματος που αναπαρίσταται σε ένα πεδίο συχνοτήτων λαμβάνεται με την πραγματοποίηση ανάλυσης γραμμικής πρόβλεψης σε μια κατεύθυνση της συχνότητας με τη χρήση μιας μεθόδου συνδιακύμανσης ή μιας μεθόδου αυτοσυσχέτισης. Μετά από τη ρύθμιση της ισχύος του φίλτρου των συντελεστών γραμμικής πρόβλεψης, πραγματοποιείται φιλτράρισμα στην κατεύθυνση της συχνότητας στο σήμα με τη χρήση ρυθμισμένων συντελεστών, μέσω των οποίων σχηματίζεται ο χρονικός φάκελος του σήματος. Αυτό μειώνει την εμφάνιση προ-ηχούς και μετά-ηχούς και βελτιώνει την υποκειμενική ποιότητα του αποκωδικοποιημένου σήματος, χωρίς να αυξάνεται σημαντικά η ροή δυαδικών στοιχείων σε μια τεχνικής προέκτασης του εύρους ζώνης στο πεδίο συχνότητας που αναπαρίσταται από τη SBR.
