| 摘 要： | 为去除心电信号中的各种噪声,本文以小波变换的多分辨率分析为理论基础,利用自适应阈值调整小波变换系数,用调整后的系数进行心电信号重建。采用MIT-BIH数据库中的心电信号进行仿真、验证,有效地去除了噪声信号。与传统滤波器具去噪相比有明显的优越性。

| Abstract: | In order to remove all kinds of noise in the ECG,in this paper,we use the wavelet adaptive threshold denoising method which takes use of the multi-resolution feature of the wavelet transform.ECG has been reconstructed using of the adjusted coefficients.Through MIT-BIH database ECG simulation and verification,we can effectively eliminates noise.This method has obvious advantages compared with the conventional filter denoising. |
