Abstract

Foreliggende oppfinnelse angår en fremgangsmåte og et system for kompensering av Dopplerforskyvning i et signal som overføres mellom en mobilstasjon og en basestasjon i et mobil- kommunikasjonssystem. l fremgangsmåten bestemmes en Doppler-egenskap for to utvalgte deler av det mottatte signalet, hvor Doppler-egenskapen er i form av en faseforskyvning for hver utvalgt del. Den største faseforskyvningen benyttes så som en Doppler-egenskap for å tilveiebringe en Dopplerfor- skyvnings-kompensasjon for det mottatte signalet.
