Abstract

For å sikre nayaktlgheten av informasjon som sendes over et nettverk, må inltlerlngen av meldingen utvetydig Identifiseres. I den foreliggende oppfin- nelse består intermeldlngsavstanden av en serie av Identiske logiske signaler som overskrider en minimumsverdi som skiller dette Intervallet fra et meldingstegn. Meldlngstegnet har forutdefinert lengde med et startbitposisjon og et stoppbltposlsjon logisk signal som avgrenser tegnet som har de samme forut- bestemte logiske signaler for hvert meldingstegn. Tegnet har minst en ytterligere ikke-dataposisjon som har et første logisk signal for det initielle tegnet av en melding og det komplementære logiske signalet for de resterende tegn i meldingen.
