Abstract

En fremgangsmåte for trådløs kommunikasjon for å utnytte de radiofrekvente (RF) fysiske omgivelser for å etablere et tilstrekkelig antall av flere brukbare veier for RF-utbredelse for å lette kommunikasjon. Fremgangsmåten er innrettet i et trådløst kommunikasjonssystem som inkluderer minst én sender og minst én mottaker. Mottakerens antenne er rettet mot én av en mengde av mottaksveier og mottar en datastrøm fra senderen via mottaksveien som mottakerantennen er rettet mot. Mottakeren dekoder datastrømmen, rekonstruerer et modulasjonsmønster av den dekodede datastrømmen og trekker den rekonstruerte datastrømmen fra en sum av alle signalene mottatt av mottakeren via mottaksveiene. Mottakeren tilgjengeliggjør mottatt signalretningsinformasjon forbundet med mottaksveiene til senderen. Senderen justerer og/eller fjerner én eller flere av de mottaksveiene som er ubrukelige basert på signalretningsinformasjonen.
