Abstract
Et flertall av datasignaler blir mottatt over en antennegruppe som har et flertall av antenneelementer. Datasignalene blir sendt over et delt spektrum i et trådløst kommunikasjonssystem. Et signal som har hvert av datasignalene blir mottatt over hvert antenneelement. Flertallet av datasignaler blir gruppert i et flertall av grupper. De mottatte signalene i antenneelementene blir tilpasset filtrert (70) i en første gruppe av flertallet av grupper, som produserer et tilpasset filtrert resultat. Data blir felles detektert i den første gruppen ved å bruke det tilpassede, filtrerte resultatet. Et interferenskorreksjonssignal blir konstruert (76) ved å bruke de detekterte data for hvert antenneelement. Det interferenskansellerte resultatet blir subtrahert (92) fra det mottatte signalet i hvert antenneelement, som produserer et interferenskansellert resultat for hvert antenneelement. Data blir suksessivt detektert for gjenværende grupper ved å bruke det interferenskansellerte resultatet for hvert antenneelement.
