The authors propose a 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[dB]about3[dB] better than that of improved VBR-MPCM.
