Abstract

Oppfinnelsen angår en mottaker og en fremgangsmåte for mottaking av et signal fra en ønsket bruker, hvilket signal kan ankomme til mottakeren langs flere forskjellige baner (112,114, 116) med flere forskjellige forsinkelser, og hvilken mottaker omfatter en antennegruppe (500, 700-704) som består av flere elementer, og hvor en eller flere kanalenheter (504-508, 738-742) omfatter minst en anordning (620, 804) for demodulering av den ønskede, mottatte signalkomponent. For å oppnå stor spektral virkningsgrad omfatter kanalenheten (504-508, 738-742) i basestasjonen ifølge oppfinnelsen en anordning (604, 732, 802) for å søke etter de mottatte signalkomponentenes innkommende retninger og forsinkelser, og en anordning (604, 732, 802) for å indikere de beste komponentenes parametere. overfor demoduleringsanordningene (600, 602, 804-808).
