VERFAHREN UND VORRCHTUNG ZUR CELP KODIERUNG UND DEKODIERUNG

摘要

A multi-codebook fixed bitrate CELP signal block encoder/decoder includes a codebook selector ( 22 ) for selecting, for each signal block, a corresponding codebook identification in accordance with a deterministic selection procedure that is independent of signal type. Included are also means for encoding/decoding each signal block by using a codebook having the selected codebook identification.
