Abstract

Oppfinnelsen angår en fremgangsmåte for overføring, og et radiosystem som omfatter minst en sender (200) og en mottaker (100) som benytter TDD-dupleksing, når de setter opp en forbindelse. Senderen (200) mottar signaler som har forplantet seg langs forskjellige signalbaner, ved hjelp av antenner (201). Radiosystemet omfatter senderanordninger (220) som mottar et signal fra flere polarisasjonsretninger, og måleanordninger (210) som måler signaler som mottas med senderen (200), hvor disse signalene kombineres til ett signal på grunnlag av målingen. Senderanordningene (220) polariserer signalet, og sender det polariserte signalet til mottakeren (100) i flere polarisasjonsretninger, på grunnlag av målingen som utføres med måleanordningene (210).
