Abstract

Oppfinnelsen angår en fremgangsmåte for dataoverføring, anvendt i et radiosystem av CDMA-type. En basestasjon og flere terminalutstyr utveksler data i det minste i en pakkesvitsjet modus, og et terminalutstyr sender til basestasjonen, på en direkte tilgangs-kanal, et direkte tilgangs-signal som omfatter minst en innledning (100) og en datadel (102) multiplisert med en spredningskode. Et forhåndsbestemt sett av spredningskoder og signatursekvenser (104) er lagret i terminal- utstyret, og hver signatursekvens (104) bestemmer en spredningskode. Terminalutstyet velger en signatursekvens (104) blant settet av signatursekvenser, ved hjelp av en vilkårlig prosess, og legger den . valgte signatursekvensen (104) til direkte tilgangs-signalets innledning (100). Videre benytter terminalutstyret den spredningskode som tilsvarer den valgte signatursekvensen (104), i datadelen (102) av direkte tilgangs-signalet. Interferenskansellering utføres i basestasjonen i samsvar med signatursekvensen (104) i det mottatte direkte tilgangs- signalets innledning (100), slik at i det minste den interferens som forårsakes av den mottatte datadelen (102), elimineres fra minst ett annet mottatt signal, for å forbedre deteksjonen.
