Abstract

Oppfinnelsen angår en fremgangsmåte for bestemmelse av forbin- delseskvalitet i en mottaker i et celledelt radiosystem, og en mottaker som omfatter en anordning (25) for dekoding av et mottatt signal i samsvar med Viterbi-algoritmen, hvilken anordning (25) beregner estimater av verdien (the merit) av avgjørelsene som foretas, i tillegg til å dekode de mottatte symbolene. For å forbedre estimerings-nøyaktigheten av bitfeilraten over forbindelsen mellom senderen og mottakeren, spesielt med lave bit-tall, omfatter mottakeren ifølge oppfinnelsen anordninger (28, 29) for å beregne bitfeilraten over forbindelsen på grunnlag av de beregnede estimatene.
