Abstract

Παρέχεται μια μέθοδος μετάδοσης ορθογώνιας πολυπλεξίας διαίρεσης συχνότητας (OFDM) που περιλαμβάνει μια μονάδα επεξεργασίας δεδομένων η οποία παράγει ένα σήμα μετάδοσης, χρησιμοποιώντας ένα πλήθος από τόνους, συμπεριλαμβανομένου ενός δεσμευμένου τόνου, μιας μονάδας αποθήκευσης που αποθηκεύει πληροφορίες Πυρήνα μείωσης κορυφής σύμφωνα με τον τύπο του συμβόλου δεδομένων, και μια μονάδα αντιστάθμισης που ανακτά τις πληροφορίες Πυρήνα μείωσης κορυφής, σύμφωνα με τον τύπο του συμβόλου δεδομένων από τη μονάδα αποθήκευσης και οδηγεί τις ανακτηθείσες πληροφορίες να μεταφέρονται από τον δεσμευμένο τόνο που περιλαμβάνεται στο σήμα μετάδοσης. Ως εκ τούτου, ο λόγος κορυφής προς μέση ισχύ (PAPR) μπορεί να αντισταθμιστεί με τρόπο αποτελεσματικό.
