Abstract

Den foreliggende oppfinnelse vedrører en frem- gangsmåte for koding og overføring av en digital melding (c(x)) omfattende et første antall av informasjonsbiter (a(x)) og et andre antall av styrebiter (b(x)), idet meldingen eller kode- ordet normalt overføres kontinuerlig, samt en fremgangsmåte for mottagning og dekoding av en slik digital melding. For å kunne tillate en pålitelig blokksynkronisering og feildetektering er det i henhold til oppfinnelsen foreslått et kodeformat ved hvilket man unngår behovet for å vente på starten av en blokk eller en melding, og ved hvilket det tillates verifikasjon før synkronisering.The present invention relates to a method of encoding and transmitting a digital message (c (x)) comprising a first number of bits of information (a (x)) and a second number of control bits (b (x)), the message or the password is normally transmitted continuously, as well as a method for receiving and decoding such a digital message. In order to allow for reliable block synchronization and error detection, the invention proposes a code format which avoids the need to wait for the start of a block or message and permits pre-synchronization verification.
