摘要：It is inevitable that noises will be introduced during the acquisition of pulse wave signal, which can result in morphology changes of the original pulse wave, and affect the hemodynamic analysis and diagnosis based on pulse wave signalsIn order to remove these noises, an adaptive de-noising method based on empirical mode decomposition (EMD) and wavelet threshold is proposed in this paperCompared with the wavelet threshold method for denoising pulse wave, the proposed approach is more effective, especially at low signal-to-noise ratio.
