Abstract

I et mobilkommunikasjonssystem beskrives en fremgangsmåte og en krets for symbolestimering. Ifølge fremgangsmåten estimeres en myk-utgangs- avgjørelse for et symbol, og avgjørelsen tilbakekoples for å modifisere avgjørelser som foretas for et etterfølgende sett med mottatte sampler. Dette har den fordel at ikke bare informasjon befordres om det mest trolige symbol, men også informa- sjon om støymiljøet.
