Optimized wavelets for blind separation of nonstationary surface myoelectric signals.
IEEE Transactions on Biomedical Engineering(2008)
摘要
Surface electromyography (EMG) signals detected over the skin surface may be mixtures of signals generated by many active muscles due to poor spatial selectivity of the recording. In this paper, we propose a new method for blind source separation (BSS) of nonstationary signals modeled as linear instantaneous mixtures. The method is based on whitening of the observations and rotation of the whitene...
