Robust Algorithm for EMG signal Amplitude Estimation in noisy Environment
잡음환경에 강건한 근전도 신호 진폭 추정 알고리듬 제안
Abstract
This paper has been studied an algorithm for EMG signal amplitude estimation in noisy environment. The proposed method has the first stage decomposing the row vector from the delayed EMG signal and the second stage computing the eigenvalues by the eigen decomposition from the covariance matrix of the EMG signal matrix. The last stage is the estimation of RMS values from the eigenvalues. The proposed method was effective when the amplitude of the EMG signal is small, which means the signal to noise ratio is low.
