Abstract

En fremgangsmåte for rammesynkronisering i en mottaker i et trådløst kommunikasjonssystem hvor data blir sendt i rammeenheter i et flerveismiljø begynner med å trekke ut datasampler for en forhåndsbestemt vindusstørrelse. En treningssekvens tilsvarende en gitt celleparameter blir generert. Dataene blir korrelert med treningssekvensen over forskjellige forsinkelser for å lokalisere posisjonen til den første signifikante veien, som definerer begynnelsen av rammen. De korrelerte data blir akkumulert N ganger for hver forsinkelsesposisjon for å produsere i det minste en akkumulasjonsvektor.En mest signifikant veiverdi og posisjon blir bestemt som er den største verdien blant akkumulasjonsvektorene. En rammesynkroniserings korreksjonsverdi blir beregnet basert på forskjellen mellom den første signifikante veiposisjonen og en konstant kalt rammeawik. Rammesynkroniseringen blir justert basert på rammesynkroniserings korreksjonsverdien.
