Abstract

Ένας δέκτης με εξάρτημα συνδυασμού χρονικού διαφορισμού ανακτά σήμα ψηφιακών δεδομένων που μεταδίδεται μέσω φωνητικού καναλιού ενός ψηφιακού ασύρματου δικτύου τηλεπικοινωνιών. Ένα δομοστοιχείο εξαγωγής χαρακτηριστικών λαμβάνει κυματομορφή ακουστικής συχνότητας που κωδικοποιεί το σήμα ψηφιακών δεδομένων και παράγει διάνυσμα χαρακτηριστικών το οποίο αντιπροσωπεύει το σήμα ψηφιακών δεδομένων. Ένα δομοστοιχείο εκτίμησης ακολουθίας δυαδικών ψηφίων αναλύει το διάνυσμα χαρακτηριστικών και παράγει εκτιμώμενη ακολουθία δυαδικών ψηφίων που αντιστοιχεί στο σήμα ψηφιακών δεδομένων. Εάν η εκτιμώμενη ακολουθία δυαδικών ψηφίων περιέχει σφάλματα, το διάνυσμα χαρακτηριστικών αποθηκεύεται σε μνήμη. Ένα εξάρτημα συνδυασμού χρονικού διαφορισμού παράγει δεύτερη εκτιμώμενη ακολουθία δυαδικών ψηφίων αναλύοντας το πρώτο διάνυσμα χαρακτηριστικών σε συνδυασμό με ένα ή περισσότερα διανύσματα χαρακτηριστικών που είναι αποθηκευμένα στη μνήμη.
