Abstract

Foreliggende oppfinnelse har mange aspekter. Et aspekt av oppfinnelsen er å utføre utjevning ved å bruke en glidevindusfremgangsmåte. Et andre aspekt bruker om igjen informasjon utledet for hvert vindu for bruk i et etterfølgende vindu. Et tredje aspekt bruker en diskret Fouriertransformbasert fremgangsmåte for utjevningen. Et fjerde aspekt er relatert til håndtering av oversampling av de mottatte signalene og kanalresponser. Et femte aspekt er relatert til håndtering av flere mottakerantenner. En sjette utførelse er relatert til håndtering både av oversampling og flere mottakerantenner.The present invention has many aspects. An aspect of the invention is to perform leveling using a sliding window method. A second aspect again uses information derived for each window for use in a subsequent window. A third aspect uses a discrete Fourier transform-based method of equalization. A fourth aspect is related to the handling of oversampling of the received signals and channel responses. A fifth aspect is related to the handling of multiple receiver antennas. A sixth embodiment is related to handling both oversampling and multiple receiver antennas.
