Abstract

Il procedimento della presente invenzione esegue prima una sincronizzazione sui messaggi in arrivo dalla stazione di base. La prima parola di dati viene ricevuta e memorizzata nel radiotelefono. Il codice d'errore nella parola di dati viene successivamente verificato per determinare se nella parola esistono errori. Se vi sono errori, la parola viene corretta. Questo procedimento viene ripetuto su un'altra parola di dati e la seconda parola ricevuta viene confrontata con la prima. Se le parole non sono uguali, il ricevitore rimane inserito fino a che almeno due parole sono uguali e viene ricevuta l'intera lunghezza del messaggio. Se le parole sono uguali, la parola viene elaborata dal radiotelefono ed il ricevitore viene disinserito per la restante porzione del messaggio fino a che deve essere ricevuta la successiva parola di sincronizzazione.
