Abstract

Fremgangsmåte og anordning for detektering av deviasjon, for bruk under overføring av et faseskiftmodulert informasjonsbærende signal mellom en sender og en mottaker. Deviasjonsdetektoren gjør bruk av tilstedeværelsen av faselineære segmenter, dvs. deler av sekvenser av faseendringer med fortløpende samme faseendring. Deviasjonsdetektoren ekstraherer segmenter som består av tre eller flere fortløpende faseendringer med fastslått samme faseendring. Identifisering av de utfiltrerte segmentene blir utført for å kunne slå fast hvilke nominelt faselineære sekvenser segmentene tilhører. Deretter er det mulig å beregne deviasjonen og eventuelt et korreksjonssignal.
