Abstract
Oppfinnelsen angår en fremgangsmåte for synkronisering og en mottaker som benyttes i et radiosystem hvor synkronisering foretas i forhold til et mottatt signal, og radiosystemet omfatter minst en mottaker (100, 200, 300) som mottar et modulert og delvis tidligere kjent signal som består av symboler, og hvor signalet inneholder tids- og frekvensawik. Mottakeren omfatteren multipliseringsanordning (402) for å multiplisere det mottatte signalet med den kjente delen av det mottatte signalet for å oppnå et produkt, en transformanordning (403) for å korrelere produktet for å oppnå et forhold, og en sammenligningsanordning (404) for å sammenligne forholdet med en på forhånd oppsatt korrelasjon-terskelverdi, og på grunnlag av denne sammenligningen foretas en avgjørelse om synkronisering med det mottatte signalet.
