Abstract

Det er beskrevet en anordning og fremgangsmåte ved søk etter overføringsvei og en mottageranordning med en gruppeantenne som bruker disse for mottagning av et signal ifølge DS-CDMA-metoden ved hjelp av en gruppeantenneenhet bestående av flere antenneelementer for å påvise tidsstyringen for flere overføringsveier. l et signalmottagende system som har flere gruppeantenneenheter (141, 142) syntetiseres en forsinkelsesprofil for hvert av antenneelementene (11 - 16). Påvisning av overføringsvei utføres ved hjelp av denne syntetiserte avgivelse for derved å muliggjøre påvisning med større nøyaktighet og høyere hastighet. Ikke bare forsinkelsesprofilen for hvert antenneelement, men også en forsinkelsesprofil mellom gruppeantenneenheter (multimottagningsgrener) kan syntetiseres. Når det dannes en stråle i en søkerseksjon (44) syntetiseres videre en forsinkelsesprofil for en lik retning gruppeantenneenhetene imellom.
