摘要:
In an ADPCM encoding and decoding system comprising an encoder having an adaptive predictor and an adaptive quantizer and a decoder having an adaptive predictor and an inverse adaptive quantizer, the adaptive predictors each comprise: an adaptive-zero predictor of an arbitrary order and an adaptive-pole predictor of an arbitrary order, for input signals with time-varying frequency components; a fixed-pole predictor of an arbitrary order, for input signals the frequency composition of which remains substantially invariant over time; and an offset predictor for rejecting an offset component of the input signals, these elements being connected in series. The adaptive-zero and adaptive-pole predictors generate estimates for voice signals with time-varying frequency components. The fixed-pole predictor generates estimates for voiceband data signals the frequency components of which remain substantially invariant over time. The adaptive predictors effectively operate for voice and voiceband data signals, providing a higher prediction gain. The quantizer provides a stably higher signal-to-quantization noise ratio for modem signals.
