Abstract

Oppfinnelsen bestemmer den geografiske posisjonen til en abonnentenhet i et CDMA kommunikasjonssystem. I det minste en basestasjon sender et spredt spektrum signal med en bitvis kodesekvens som er unik for denne basestasjonen. En abonnentenhet mottar basestasjonens signal og sender et spredt spektrum signal med en unik bitvis kodesekvens tidssynkronisert med den bitvise kodesekvensen til det mottatte basestasjonssignalet. Basestasjonen mottar abonnentens signal og sammenligner den bitvise kodesekvensen til det mottatte abonnentsignalet med det bitvise kodesekvens signalet sendt av basestasjonen for å bestemme posisjonen til abonnentenheten.
