Abstract

En fremgangsmåte for å detektere en dataskur for oppsett av et anrop, og en mottaker i et digitalt radiosystem, hvor mottakeren omfatter en omformer (304) for å sample et signal som mottas i en gitt tidsluke, en anordning (400) for å korrelere digitaliserte sampler med en kjent treningssekvens, og en anordning (402) for å beregne energien i de oppnådde korrelasjonsresultatene, en anordning (404) for å lete etter maksimumsverdiene i en streng av sampler av gitt orden blant de beregnede energier, og en anordning (408) for å ta gjennomsnittet av maksimumsverdiene som blir funnet, for ett sampel. For å forbedre påliteligheten ved deteksjon av en skur for oppsett av anrop, omfatter mottakeren en anordning (410) for å beregne gjennomsnittet av energien i de andre samplene i tidsluken for ett sampel, og en anordning (412) for å sammenligne de gjennomsnittsberegnede maksimumsenergi-verdiene med energiverdiene for de andre samplene.
