Abstract

En kommunikasjonsinnretning for å avskille kildesignalet tilveiebrakt av M signalkilder inkluderer en antennegmppe innbefiattende N antenneelementer fior å motta minst N ulike summeringer av de M kildesignalene. En kodeavspreder er koblet til de N anteimeelementene fior å dekode de minst N ulike summeringer av de M kildesignalene. Hver av de N ulike summeringene inkluderer k koder fior å tilveiebringe k ulike summeringer av de M tilhørende kildesignalene. En blindsignalavskillelsesprosessor danner en blandingsmatrise innbefiattende minst kN ulike summeringer av de M kildesignalene, og avskiller ønskede kildesignaler fira blandingsmatiisen. Blandingsmatrisen har en rang lik opptil kN.
