Abstract

Kommunikasjonsinnretning for å avskille kildesignaler tilveiebrakt av M signalkilder inkluderer en antennegruppe innbefiattende N korrelerte antenneelementer fior å motta N ulike summeringer av de M kildesignalene, der N og M er større enn 1. En mottager er koblet til anteimegmppen fior å motta de minst N ulike summeringer av de M kildesignalene. En blindsignalavskillelsesprosessor er koblet til mottageren fior å danne en blandingsmatrise innbefiattende opptil de minst N ulike summeringer av de M kildesignalene, og fior å avskille ønskede kildesignaler fi-a blandingsmatrisen. Blandingsmatiisen har en rang minst lik N.
