Abstract

Μία μέθοδος και συσκευή για ταχεία επίκτηση συγχρονισμού ενός σήματος σε σύστημα επικοινωνίας WCDMA που χρησιμοποιεί μεταβλητής διάρκειας συσσώρευση δειγμάτων, δοκιμή εγκυρότητας εκτιμήσεων αποκωδικοποιητή, και παράλληλη αποκωδικοποίηση πολλαπλών σημάτων συγχρονισμού μέσα σε ένα κανάλι PERCH. Ο δέκτης (204) συσσωρεύει τα δείγματα που είναι απαραίτητα ώστε να καθορίζεται με αξιόπιστο τρόπο ο χρονισμός θυρίδας. Έως ότου οι εκτιμήσεις χρονισμού θυρίδας επιτύχουν σε μία δοκιμή εγκυρότητας, δείγματα συσσωρεύονται (304Α, 304Β) για εκτιμήσεις χρονισμού πλαισίου. Έως ότου οι εκτιμήσεις χρονισμού πλαισίου επιτύχουν σε μία δοκιμή εγκυρότητας, δείγματα αναλύονται ώστε να καθορίζεται η μετατόπιση πιλότου του καναλιού.
