Abstract

Oppfinnelsen angår en fremgangsmåte for mottaking, samt en mottaker for mottaking av signaler som leveres fra en radiostrekning, og signalene omfatter informasjon, og hvert signal som ankommer til mottakeren, forsinkes med en sær- skilt forsinkelsesverdi. Mottakeren omfatter en anordning (30) og en fordelingsan- ordning (50) for å bestemme styrken av en del av et signal som er forsinket med en viss forplantningsforsinkelse, for flere verdier av forplantningsforsinkelsen. For- delingsanordningen (50) sammenligner forsinkelsesforskjellene for de mottatte signalene med hverandre, og danner summer av styrkene av signaldelene som er bestemt for forskjellige verdier av forplantningsforsinkelsen. Fordelingsanordnin- gen (50) velger blant de mottatte signalene de signaler som har forsinkelsesver- dier som avviker med minst en forhåndsbestemt forsinkelsesforskjell, og med sum av signaldelenes styrker som oppnår den høyest mulige verdi. Mottakeren indike- rer den mottatte informasjonen ved å benytte signalene som er valgt ovenfor.
