Abstract
Ένα σύνολο καναλιών συνδρομητών (402, 404, 411, 415) μεμονωμένης ρύθμισης κέρδους διαμορφώνεται μέσω της χρησιμοποίησης ενός συνόλου ορθογωνίων κωδίκων υποκαναλιών (Wc, Ws, Wf) που έχουν ένα μικρό αριθμό chips διεύρυνσης ΡΝ ανά περίοδο ορθογωνικής κυματομορφής. Σε δεδομένα που πρόκειται να μεταδοθούν μέσω ενός εκ των καναλιών μετάδοσης πραγματοποιείται χαμηλού ρυθμού κώδικα κωδικοποίηση διόρθωσης σφαλμάτων και επανάληψη ακολουθιών πριν τη διαμόρφωση τους με έναν εκ των κωδίκων υποκαναλιών, ρύθμιση κέρδους, και άθροιση τους με δεδομένα που διαμορφώνονται χρησιμοποιώντας τους άλλους κώδικες υποκαναλιών. Τα προκύπτοντα αθροισμένα δεδομένα (410, 420) διαμορφώνονται χρησιμοποιώντας ένα μακρύ κώδικα χρήστη και ένα ψευδοτυχαίο κώδικα διεύρυνσης (κώδικα ΡΝ) και αναβιβάζονται για μετάδοση. Η χρησιμοποίηση των βραχέων ορθογώνιων κωδίκων παρέχει καταστολή παρεμβολής ενώ επιτρέπεται ακόμη εκτεταμένη κωδικοποίηση διόρθωσης σφαλμάτων και επανάληψη για διαφορισμό χρόνου ώστε να αντιμετωπίζεται η διάλειψη Raleigh που συνήθως συναντάται σε επίγεια ασύρματα συστήματα. Το σύνολο των κωδικών υποκαναλιών μπορεί να περιλαμβάνει τέσσερις κώδικες Walsh, όπου έκαστος είναι ορθογώνιος στους εναπομείναντες κώδικες του συνόλου. Η χρησιμοποίηση τεσσάρων υποκαναλιών προτιμάται καθώς επιτρέπει τη χρησιμοποίηση βραχύτερων ορθογώνιων κωδίκων, εν τούτοις, η χρησιμοποίηση ενός μεγαλύτερου αριθμού καναλιών και επομένως μακρύτερων κωδίκων είναι αποδεκτή. Κατά προτίμηση, τα δεδομένα πιλότου μεταδίδονται μέσω ενός πρώτου εκ των καναλιών μετάδοσης και τα δεδομένα ελέγχου ισχύος μεταδίδονται μέσω ενός δεύτερου καναλιού μετάδοσης. Το μήκος, ή ο αριθμός chips, σε κάθε κώδικα καναλιού μπορεί να
