Abstract

Den foreliggende oppfinnelsen angår en fremgangsmåte og system for multirate gittervektorkvantisering av en kildevektor x som representerer en ramme fra et kildesignal som for eksempel skal anvendes i digitale overførin 's- og lagringssystemer. Fremgangsmåten for multirate gittervektorkvantisering omfatter trinnet med å assosiere et gitterpunkt y i et ubundet gi etter A til x; verifisering dersom y er inkludert i basiskodebok C utledet fra gitteret A; dersom dette ikke e r tilfelle, så indeksering av y i C for slik å gi kvantiseringsindekser. Dersom ikke så utvidelse av basiskodeboken ved for eksempel anvendelse av en Voronoi-basert utvidelsesfremgangsmåte, som resulterer i en utvidet kodebok; assosiering av en kodevektor c fra den utvidede kodeboken til y, og indeksering av y i den utvidede kodeboken C. Utvidelsesteknikkene tillater å oppnå høyere bitratekodebøker fra basiskodebøkene sammenlignet med kvantiseringsfremgangsmåter og systemer av kjent type.
