Abstract

Oppfinnelsen angår tolking av et overført signal fra signaler som oppnås på signalmottakingssiden fra en antennevektor som innbefatter flere antenne- elementer. Ideen ifølge oppfinnelsen er å tolke signalet i to trinn, l det første trin- net dannes det retningsinnstilte signalstråler av det flerdimensjonale signal som oppnås fra antennevektoren. l det andre trinnet innmates de retningsinnstilte sig- nalene i et element for optimal sammensmelting, som utleder det overførte signa- let fra flere signalgrener som benyttes som innmating.
