Abstract

En mottaker som inkluderer minst et utlignerfllter og en tappkoefflsientgenerator for å implementere mottakerdiversitet. Utlignerfllteret behandler et signal avledet fra signaler mottatt av et flertall av antenner. I en utførelsesform fusjoneres sampledatastrømmer flia antennene inn i en sampledatastrøm. Den fusjonerte sampledatastrømmen behandles av et enkelt utvidet utlignerfllter, hvorved fllterkoefifisientene justeres i overensstemmelse med et felles feilsignal. Et fllterkoefiEisient korrigeringsledd brukt av utlignerfllteret dannes av tappekoefifisientgeneratoren ved å bruke en normalisert minste middelkvadrat (NLMS) algoritme. I en annen utførelsesform utnyttes et flertall av utlignerflltre, hvorved hver utligner mottar en sampledatatrøm flia en spesiflkk av antennene. I enda en ytterligere utførelsesform kombineres sampledatastrømmene etter å ha blitt behandlet av flertall av tilpassede flitre basert på henholdsvis beregnede kanalimpulsresponser.
