Abstract

Oppfinnelsen angår en fremgangsmåte for å kombinere signaler, samt en mottaker som implementeres etter RAKE-prinsippet. Mottakeren omfatter et antall grener som den mottar et signal ved hjelp av. Mottakeren omfatter en forhånds- kombineringsanordning som etter behov kombinerer signaler som mottas via mottakerens grener, en senderanordning for å sende de forhåndskombinerte sig- nalene etter behov videre til en andre mottaker, og en kombineringsanordning for å kombinere signalene som mottas via mottakergrenene, med det forhåndskombi- nerte signalet.
