为了能够快速简单的滤除心电噪声，提高信号的信噪比，采用分数阶小波变换对心电信号进行处理，并利用“Arrhythmia Database”和“Noise stress Test Database”数据库中的数据和对其进行验证。仿真结果表明，运用这种方法能够有效地提高心电信号的信噪比，清晰的还原出心电信号的波形及其特点。所以分数阶小波变换在心电信号去噪处理中具有很好的应用。

In order to rapidly and simply filter the electrical noise and improve the signal noise ratio , the fractional transform was used to process the Electrocardio signal (ECG)“Arrhythmia Database”and“Noise stress Test Database” were used to verify it .The simulation results show that this method can not only improve the ECG signal noise ratio effectively ,but also restore the clear waveform and its characteristics .So the fractional wavelet transform finds a good application in the ECG signal noise processing .
