Abstract

Robust system for undervannskommunikasjon, for kommunikasjon mellom en akustisk signalsender og en fjernt plassert, akustisk signalmottaker, der de sendte dataene bæres av et flertall av symboler, der hvert symbol har to komponenter, hvorav ett omfatter en distinktiv bitkode og det andre vedrører karakteren til symbolet som et hele, der karakteren av suksessive symboler steppes igjennom i en forutbestemt, kontinuerlig repeterende sekvens av distinktive trinn, der hvert opptrer en gang i sekvensen, og der signalmottakeren opereres synkront med signalmottakeren og omfatter et korrelatorsarrangement som er reaksjonsfølsomt både for bitkoden og for karakteren til mottatte signaler, for å effektuere demodulasjon og å ha et flertall av utganger for hvert symbol, slik at i det hvert symbol detekteres, dominerer et signal på utgangen som det tilsvarer, og amplitudedeteksjonsanordningene som er reaksjonsfølsomme for utgangene fra korrelatorsarrangementet for å gi et utgangssignal som tilsvarer de sendte dataene.
