Abstract

Oppfinnelsen angår en fremgangsmåte og et system for digital signalover- føring, l denne fremgangsmåten (302) kodes et signal for å minimalisere over- føringsfeil på en overføringskanal, og (308) det kodede signalet sendes gjennom minst to basestasjoner. Et brukerutstyr mottar (310) så det kodede signalet, og kodingen av det mottatte signalet blir dekodet (312). Fremgangsmåten kjenneteg- nes i samsvar med oppfinnelsen ved at.det kodede signalet deles (304) i separate signaldeler med i det minste delvis forskjellig innhold. Så indikeres (306) en spe- siell signaldel for hver basestasjon, og basestasjonene sender (308) sine spe- sielle signaldeler. Ved mottakingen (312) kombineres informasjonen i de mottatte signaldelene.
