Abstract

Oppfinnelsen angår en sende-fremgangsmåte og et celledelt radiosystem som omfatter basestasjoner og minst en vokoder. Basestasjonene og vokoderen sender et signal til hverandre. Basestasjonene sender et signal til vokoderen hovedsakelig samtidig, og vokoderen mottar de samtidig utsendte signalene på forskjellige mottakings-tidspunkter. Det celledelte radiosystemet omfatter en sammenligningsanordning for å sammenligne signalenes mottakings-tidspunket med et forutbestemt tidsvindu, en måleanordning for å måle og sammenligne kvaliteten av de mottatte signalene, og en velgeranordning for å utvelge et signal på grunnlag av den ovennevnte signalmålingen og sammenligningen.
