Abstract

En valgt kanal av et flerkanalssignal som representeres av rammer som består av samplingsverdier med en høy tidsoppløsning kan kodes med høyere kvalitet når en bølgeformparameterfremstilling som representerer en bølgeform av en mellomliggende oppløsningsfremstilling av den valgte kanal blir avledet, idet bølgeformparameterfremstillingen omfatter en sekvens av mellomliggende bølgeformparametere med en tidsoppløsning som er lavere enn høytidsoppløsningen av samplingsverdiene og høyere enn en tidsoppløsning som definert av en rammerepetisjonsrate. Bølgeformparameterfremstillingen med den mellomliggende oppløsning kan brukes for å forme en rekonstruert kanal for å gjenvinne en kanal med en signalomsluttning som er nær den valgte, opprinnelige kanal. Tidsskalaen som formingen utføres på er kortere enn tidsskalaen for en rammevis behandling og forbedrer således kvaliteten av den rekonstruerte kanal. På den annen side er formingstidsskalaen større enn tidsskalaen av samplingsverdiene, hvilket vesentlig reduserer mengden av data som trengs for bølgeformparameterfremstillingen.
