Abstract

Oppfinnelsen angår en fremgangsmåte for mottaking, og en mottaker i et system som i hver celle omfatter en basestasjon som kommuniserer med terminaler som befinner seg i dens område. Et mottatt signal omfatter et sumsignal av signaler som kommer fra flere sendere. Mottakeren omfatter en anordning (208) for å utføre interferens-eliminering og samtidig flerbruker- deteksjon på signalet, og en anordning (210) for å søke signalparametere. For å redusere den nødvendige beregningskapasiteten omfatter mottakeren videre en anordning (210) for å fjerne virkningen av de kjente brukernes signaler fra det mottatte sumsignalet, og en anordning (210) for å estimere de ukjente signalenes parametere fra et smalbåndet restsignal.
