摘要

介绍了一种有效的自适应编码器——以LMS自适应预测器为主体的自适应差分脉冲编码调制(ADPCM)编码器及其在振动信号压缩中的应用。给出了仿真结果并进行了分析。所描述的ADPCM编码器具有适应输入信号统计变化的优点，在这种情况下可以保持较高的压缩比。这是一种有效的振动信号压缩方法。

Vibration signal compression by an ADPCM encoder

A description is presented of an effective adaptive encoder, an adaptive differential pulse code modulation (ADPCM) encoder whose main part is a LMS adaptive predictor, and applications in vibration signal compression. Some simulation results are also presented and analyzed. The ADPCM encoder described has the advantage of adapting statistical variation of the input signal and can maintain a relatively high compression ratio in such situations. It is an effective method in vibration signal compression.<>
