Abstract

Oppfinnelsen angår en fremgangsmåte for sending og et celledelt radio- system som omfatter basestasjoner og minst en vokoder, og i det celledelte radio- systemet sender basestasjonene og vokoderen til hverandre et signal, basesta- sjonene sender signaler til vokoderen hovedsakelig samtidig, og vokoderen mottar de hovedsakelig samtidig sendte signalene på forskjellige mottakings-tidspunkter. Det celledelte radiosystemet omfatter en måleanordning for å måle forsinkelses- forskjellen mellom de forskjellige mottakings-tidspunktene for signalene som mot- tas av vokoderen, samt en forsinkelsesanordning for om nødvendig å forsinke signalene som skal sendes til basestasjonene, på en slik måte at basestasjonene mottar signalene som sendes av vokoderen, hovedsakelig samtidig.
