Abstract
Oppfinnelsen angår en fremgangsmåte for utvelgelse av et signal, samt et celledelt radiosystem som omfatter basestasjoner og en vokoder som koder et signal, hvor vokoderen er funksjonsmessig forbundet med basestasjonene via overføringsbaner av forskjellige lengder. Basestasjonene mottar et signal kodet av vokoderen i forover-retning, og sender et signal til vokoderen i revers-retning. Det celledelte radiosystemet omfatter velgeranordninger som er atskilt fra basestasjo- nene, og som er innrettet for å velge minst ett signal som skal sendes til vokode- ren, blant de signaler som mottas av basestasjonene i revers-retningen. Velger- anordningene er innrettet for å fordele til basestasjonene det signal som ankom- mer fra vokoderen i forover-retningen.
