| 摘要 |
<p>The invention relates to a speech-adaptive predictive coding system, an encoding apparatus, a decoding apparatus and an error correcting method for such system. The encoding apparatus comprises a A/D converter, a delay circuit, a quantizer, a predictor, a predictor coefficient and residual power extractor circuit and a multiplexer. The decoder comprises a multiplexer (11), an amplifier (12), a predictor (13), a restoring circuit (14), a D/A converter (15), a burst error detector (16), a delay circuit (17), a switching circuit (18), and a reflected binary code decoder (19). The speech-adaptive predictive coding system is capable of reproducing speech-signals with high quality. </p> |
