Abstract

Pronalazak se odnosi na odredjivanje pozicije mobilnog prijemnika 4 u sistemu za pozicioniranje digitalne telefonske mreze. Prvi prijemnik 3 je na poznatoj lokaciji a drugi su mobilni. Postupak ukljucuje signale predaje iz vise izvora 1, gde signali prenosa imaju format bar dela koji ima prethodno odredjene vrednosti ili dela koji se ponavlja. Vremenski pomeraj signala prenosa primljenih u svakom prijemniku 4,5 iz izvora prenosa 1 relativno prema referentnom taktu svakog prijemnika odredjuje se sa generisanjem referentnog signala zabravljenog na referentni takt. Referentni signal ima slican format sa signalima rpenosa i ukljucuje deo identican sa prethodno odredjenim vrednostima ili ponovljeni deo prijemnog signala i uporedjuje primljeni signal prenosa i referentni signal. Vremensko kasnjenje izmedju odgovarajucih signala primljenih u prijemnicima 4, 5 je odredjeno iz njihiovog relativnog vremenskog kasnjenja, cime se odredjuje pozicija drugih prijemnika 4.
