Abstract
Oppfinnelsen angår en fremgangsmåte for sending og mottaking, samt et radiosystem, l en sender (TR) spredningskodes signalene (37) som skal sendes, i en anordning (31), og de moduleres med hjelpebærebølger i en anordning (33). l en mottaker (R) demoduleres signalene i en anordning (35) og utsettes for flerbruker-deteksjon i en anordning (36) ved å benytte hjelpebærebølgene til å begrense antallet detekterbare signaler i anordningn (35). Mottakeren (TR) benytter flerbruker-deteksjon til å redusere multiaksess-interferens og korrigere frekvens-selektiv fading.
