摘要
针对采集到的表面肌电信号中含有大量噪声,无法对信号进行准确识别和分析的问题,本文提出了一种采用自适应噪声和小波分层阈值去噪的方法来完成系综经验模态分解,实现对信号的准确识别和分析。该方法首先计算CEEMDAN(complete Ensemple Empirical Mode Decomposition with Adaptive Noise)分解后的相关系数,然后对分解后的前三个IMFs进行去噪,再进行重构,重构后进行小波分层阈值去噪。经过实验对比,发现设计的这种去噪算法的去噪效果优于其他不同的全局阈值和分层阈值去噪。
CEEMDAN-Wavelet Threshold Denoising Method on sEMG
In view of the fact that the collected sEMG signal contains a lot of noise, which makes it impossible to accurately identify and analyze the signal, this paper proposes a method that complete ensemble empirical mode decomposition with adaptive noise and wavelet layered threshold denoising to achieve accurate signal identification and analysis. The method is to first calculate the correlation coefficient after CEEMDAN(Cemplete Ensemple Empirical Mode Decomposition with Adaptive Noise) decomposition, and then denoise the first three IMFs after decomposition, and then reconstruct, and then perform wavelet layered threshold denoising after reconstruction. After experimental comparison, it is found that the denoising effect of designing such a denoising algorithm is better than other different global thresholds and separate layered threshold denoising.
