Abstract

Fremgangsmåte for datasending, sender og mottaker Oppfinnelsen angår en mottaker og en datasende- fremgangsmåte i et system hvor CDMA-multiaksess- metoden benyttes, og hvor hvert datasignal (30) som skal sendes, multipliseres med en pseudovilkårlig kode (40) med en viss lengde, og med en bithastighet som er høyere enn bithastigheten til det datasignal som skal sendes. For å sikre hurtig og lite kostnadskrevende mottaking, moduleres signalet som er multiplisert med den pseudovilkårlige koden, ytterligere i fremgangsmåten ifølge oppfinnelsen, med en gruppe bølgeformer (f- . . f,,) , hvis antall er det samme som antallet bits i den pseudovilkårlige koden, og hvor frekvensen for hver bølgeform er innbefattet i det gitte frekvensdomenet. Ifølge fremgangsmåten omformes signalet i mottakeren til digital form, og multipliseres med den pseudovilkår- lige koden som har gjennomgått en invers Fourier- transformasjon, og det multipliserte signalet utsettes for en Fourier-transformasjon.
