Abstract

A variable-bit-rate modulo PCM (VBR-MPCM) scheme is proposed. The modulo amplitude and the quantization bits are varied adaptively to prevent anomaly errors and increase data-compression efficiency. It is confirmed by computer simulation that the performance of the VBR-MPCM scheme is about 5 dB to about 15 dB better than those of the conventional MPCM-AQF, ADPCM, and DPCM-AQF schemes.
