Abstract

Oppfinnelsen angår en fremgangsmåte til gjenvinning på mottakssideenden av overførte testdata i digitale datastrømmer med cellestruktur, hvor testdataene kodes ved hjelp av kodeord som autokorrelert gir diracimpuls og hvor det på mottakssiden foretas en krysskorrelasjon for dekoding. For å kunne overføre et større antall testdata kodet, blir kodeordene på sendesiden tilføyet et binært nullord (lagret ved St=l) og de forskjellige testdata (f.eks. 11101) tilordnet de forskjellige kodeord og nullordet. På mottakssiden blir det i tillegg til krysskorrelasjonen dannet en tverrsum av de mottatte kodeord og nullordet.The invention relates to a method for recovering on the receiving side end of transmitted test data in digital data streams with cell structure, wherein the test data is encoded by means of passwords which are autocorrelated giving a direct pulse and where on the receiving side a cross correlation is performed for decoding. In order to transmit a greater number of test data encoded, the passwords on the sending side are added to a binary null word (stored at St = 1) and the different test data (e.g. 11101) are assigned to the different passwords and the null word. On the receiving side, in addition to the cross correlation, a cross-sum of the received passwords and the zero word is formed.
