Abstract

Et MIMO-kommunikasjonssystem omfatter en sender, og en mottaker synkronisert med senderen. Senderen vil endre effektnivåene for hver skiktdatastrøm på tidsintervallbasis. Datastrømmene ankommer mottakeren ved forskjellige effektnivåer, hvilket vil tilveiebringe egnede forskjeller mellom de mottatte signaler for fylling av en miksingsmatrise for en signalseparasjonsprosessering.
