Abstract

Viene qui rappresentato un sistema per eliminare gli effetti degli errori di trasmissione in un flusso digitale.Esso si caratterizza per la presenza di un preditore: in caso di errore l'ascolto viene commutato sul segnale predetto; quando il segnale ricevuto torna ad essere utilizzabile l'ascolto passa dal segnale predetto al segnale ricevuto.
