Firstly, the Dopplerfiltering is performed to reduce the data dimension in temporal domain.
首先,多普勒滤波在时域执行,以减少数据的维数。
3
A nonlinear filtering method based on principle component analysis (PCA) was proposed according to the statistical characteristics of the Doppler ultrasound blood flow signal and wall thump signal.
