摘    要:给出一种新的心电图压缩方法,该方法是在小波库中通以信息熵作为代数价函数寻找最优基,实现心电图压缩。仿真结果显示,该方法压缩比大,信息损失小,能够较好的恢复原有的信号。

关 键 词:心电图 数据压缩 小波包 最优基

Abstract:The paper reports a kind of new compression method of ECG signal. The method is realized by means of wavelet packets transform based on best basis performed by Shanon Weaker entropy criterion. The result of simulation shows that this is an efficient compression method characterized by larger compression ratio and less loss, and the original signal can be recovered well.
Keywords:ECG Data compression Wavelet packets Best basis
