Abstract

Et flertall av signaler blir mottatt i et delt spektrum. Sampler av de mottatte brukersignalene blir produsert som en mottatt vektor. Den mottatte vektoren blir segmentert til et flertall av segmenter. For hvert segment vil det suksessivt bli bestemt symboler for hver bruker eller gmppe av signaler (gmppen av signaler som har tilsvarende mottatt effekt) ved å bestemme symboler for en gruppe/bruker og å fjeme et bidrag fra denne ene bruker/gmppe fra den mottatte vektoren. De bestemte symbolene tilsvarende til hvert segment blir satt sammen til en datavektor.
