Abstract

Fremgangsmåte og apparat for kodetildeling i et spektralfordelt system for trådløs kommunikasjon som benytter en synkronisert kodedelt multippelaksessprotokoll over store områder (LAS- CDMA). Fremgangsmåten bestemmer et sett med LS-koder basert på en interferensfri vindusstørrelse. En trestruktur tilveiebringer samsvar mellom den interferensfrie vindusstørrelse og settet med LS-koder. Delsett med LS-koder dannes uten kryss- korrelasjon i det interferensfrie vindu. Delsettene tildeles nabodekningsområder i systemet for å redusere interferens mellom nabostasjoner. I en bestemt utførelse bestemmer en styringsenhet delsettene og utfører tildelingen til dekningsområder innen systemet.
