Abstract

En knutepunkt-B/basisstasjons mottaker omfatter minst en antenne for å motta signaler. Hver finger i en gruppe rekonfigurerbare rakefingre mottar en flerbanekomponent for en bruker og blir tildelt en kode for brukeren, en kodefase for flerbanekomponenten og en antenne i en antennegruppe bestående av minst en antenne. Et antenne/rakefingergruppe-grensesnitt forsyner hver finger i rakefingergruppen med en utgang fra den antenne som er tilordnet vedkommende rakefinger. En kombinerer er innrettet for å kombinere de gjenvunnede flerbanekomponenter for en bruker for derved å frembringe data for denne bruker.
