Abstract
En kommunikasjonsinnretning for å avskille kildesignalet tilveiebrakt av M signalkilder inkluderer en antennegmppe innbefiattende N antenneelementer fior å generere N innled- ende anteimemønstere fior å motta N ulike summeringer av de M kildesignalene, der N er mindre enn M. Anteimegmppen inkluderer en hevningsstyreenhet fior selektivt å endre en hevning av minst N av de innledende anteimemønstiene fior å generere minst ett ytterligere anteimemønster, hvorved minst én ytterligere ulik summering av de M kildesignalene mottas. En blindsignalavskillelsesprosessor danner en blandingsmatrise innbefiattende de N ulike summeringer av de M kildesignalene, og den minst ene ytterligere ulik summering av de M kildesignalene. Blandingsmatrisen har en rang lik N pluss antallet ytterhgere ulike summeringer av de N kildesignalene mottatt ved å bruke de ytterhgere anteimemønstiene. Blindsignalavskillelsesprosessoren avskiller Ønskede kildesignaler fra blandingsmatrisen.
