Abstract

Kommunikasjonsinnretning for å avskille kildesignaler tilveiebrakt av M signalkilder inkluderer en antennegruppe innbefattende N elementer for å danne minst N antennestråler for å motta minst N ulike summeringer av de M kildesignalene, der N og M er større enn 2. En styreenhet er koblet til antennegruppen for selektivt å danne de minst N antennestrålene. En blindsignalavskillelsesprosessor danner en blandingsmatrise innbefattende opptil de minst N ulike summeringer av de M kildesignalene. Blindsignalavskillelsesprosessoren bestemmer også hvorvidt de ulike summeringer av de M kildesignalene er korrelerte eller statistisk uavhengige, og hvis ikke, samvirker så med styreenheten for å danne ulike stråler for å motta nye ulike summeringer av de M kildesignalene for å erstatte de ulike summeringer av de M kildesignalene som ikke er korrelerte eller statistisk uavhengige i blandingsmatrisen. De ønskede kildesignalene avskilles fra blandingsmatrisen ved hjelp av blindsignalavskillelsesprosessoren.
