| 摘 要： | 小波理论在心电信号去噪处理中已经得到了广泛的应用,针对不同的噪声可以采用不同的小波方法进行去噪处理。根据小波在各个尺度上的不同的带通滤波特性,利用小波变换多分辨的特点对心电信号进行滤波,并应用Matlab仿真进行实验。通过实验证明,利用不同的阈值函数及自适应阈值能较好地抑制信号中的基线漂移、工频干扰和肌电干扰,具有一定的实用价值。

| Abstract: | ECG signal denoising wavelet theory has been widely applied,the noise can be used for different methods in different wavelet denoising.Based on the wavelet scale in all the different band-pass filter characteristics using multi-resolution characteristics of wavelet transform,ECG signal filtering,and application of matlab simulation experiment.Tests show that the use of different threshold function and adaptive threshold can be better to suppress the baseline drift signal,frequency interference and electromy... |
