Abstract

Oppfinnelsen angår en fremgangsmåte for mottaking, samt en mottaker. For å fjerne interferens i et mottatt, sammensatt signal, subtraheres i fremgangsmåten smalbån- dede interferens-signalestimater (14) som tilsvarer de interfererende signalene, fra et smalbåndet, sammensatt signal (15). De smalbåndede interferens-signalestimatene (14) genereres i mottakerens interferens-kansellerings-primitivanordninger (10) ved å multiplisere en detektert bit i det interfererende signalet, med en krysskorrelasjon og et kanal-estimat for spredningskoder.
