Variable bit rate modulo-PCM using adaptive predictor

Abstract

The authors propose an improved variable bit rate modulo-PCM (VBR-MPCM). It has the same performance as conventional VBR-MPCM, but it has lower complexity and shorter time delay. The authors also propose variable bit rate modulo-PCM using adaptive predictor (VBR-MPCM-AP) which differs in that it has an adaptive rather than fixed predictor. Its performance is about 0-3 dB better than that of improved VBR-MPCM.<>
