Abstract

Oppfinnelsen angår en fremgangsmåte for diversitets-kombinering, og en mottaker. Ved diversitets-kombinering vektlegges utgangssignalene (33) fra et tilpasset filter (25) i hver gren, med et kvalitets-estimat (32) som genereres i en kvalitetsanordning (28b) på en slik måte at kvalitets-estimatet (30) er proporsjo- nalt med den inverse av signalets interferens-styrke (31). Styrken (31) av signal- interferens genereres i en interferensanordning (28c), f.eks. på varians-lignende måte, fra forskjellene mellom et referansesignal (30) som genereres i en referan- se-signalanordning (28a) som foldingen av den estimerte kanal-impulsresponsen og den forutbestemte sekvensen, og et signal mottatt fra kanalen.
