Abstract

Et MIMO kommunikasjonssystem inkluderer en sender, og en sendeantennerekke koblet til senderen og har M antenneelementet for å sende M kildesignaler. En mottaksantennerekke er koblet til en mottager og har N antenneelementer for å motta i det minste M ulike summeringer av de M kildesignalene, der N er mindre enn M. En signal-atskillelsesprosessor er koblet til mottageren for å danne en blandingsmatrise som inkluderer de i det minste M ulike summeringer av de M kildesignalene slik at blandingsmatrisen har en rang lik med i det minste M. Signalatskillelsesprosessoren atskiller ønskede kildesignaler fra blandingsmatrisen.
