Abstract
Når en inngangstale (5) deles opp i en spektrum-omhylningsinformasjon og et eksiteringssignal, og eksiteringssignalet kodes i hver båndkolonne på basis av flere eksiteringssignal-posisjoner og flere eksiteringssignal-forsterkninger, så kan kodingskarakteristikken forbedres i samsvar med foreliggende oppfinnelse, l en eksiteringssignal-kodingsenhet (11) for koding av eksiteringssignalet basert på flere eksiteringssignalposisjoner og flere eksiteringssignal-forsterkninger, er det opprettet en beregningsenhet (40) for å beregne en midlertidig forsterkning for hver posisjonskandidat for eksiteringssignalet. En søkenhet (41) for pulsposisjoner bestemmer de flere eksiteringssignalposisjoner ved bruk av de midlertidige for- sterkninger. En forsterknings-kodingsenhet (12) koder eksiteringssignal-forsterkningen basert på de fastlagte eksiteringssignalposisjoner.
