| 摘 要： | 小波包函数族是小波函数的推广，与一般的小波函数相比小波包函数具有更好时频局域特性。本文在小波包理论的基础上对医学上常用的心电图信号（ＥＣＧ）进行了数据压缩实验。实验结果表明，在不影响诊断分析的条件下，小波包压缩技术可以达到令人满意的效果。

| Abstract: | The wavelet packet is the extension of traditional wavelet basis funtion.It has much better time frequency localization character than traditional wavelet.In this paper we compress the data of ECG signal by using the algorithm based on wavelet packet.The result show that by this compression algorithm satisfied compression result can be obtained. |
