Abstract

Oppfinnelsen angår en fremgangsmåte for mottaking som skal brukes i et CDMA-system, samt en CDMA-mottaker, bestående av en antenne (40), radiofrekvensdeler (41), en A/D-omformer (42), et adaptivt, lineært fortrinn (43a til 43d) og en adaptiv, ikke-lineær detektoranordning (44) , hvor detektoranordningen (44) detekterer flere brukeres signaler samtidig og reagerer på et mottatt signal ved å korrigere parametere som skal brukes for deteksjon, til å tilsvare signaltilstander i det mottatte signal. For en optimal deteksjon av det mottatte signal, overvåker et utgangssignal fra det lineære fortrinn (4 3a til 4 3d) i mottakeren ifølge oppfinnelsen, innstillingen av parametrene for den adaptive, ikke-lineære detektoranordning (44).
