Abstract
Oppfinnelsen angår en fremgangsmåte for mottaking i et digitalt, celledelt radiosystem. Oppfinnelsen angår videre en mottaker i det celledelte radionettet. Ved beregning av signal/støy-forholdet benyttes et referansesignal som er kon-volveringen av den estimerte pulsresponsen for en kanal, og den forutbestemte sekvensen (53). Signal/støy-forholdet oppnås som et forhold mellom variansen for referansesignalet og den forutbestemte sekvensen (53) som mottas fra kanalen. Signal/støy-forholdet benyttes for å vektlegge diversitetsmottakerens diversitets-grener.
