Abstract

Synkronisering av en mottaker, generelt ved prosessering av multiplekssignaler med ortogonal frekvensdeling, oftest benevnt OFDM-signaler. Mottakeren som synkroniseres på denne måte tar imot innkommende flerbærersignaler av typen OFDM, og betydelige reduksjoner kan oppnås i bereg- ningene av effekt, utførelseshastighet og nøyaktighet ved å bygge på at kjente meto- der har en betydelig grad av redundans.
