“…Movement artifacts affect both the PPG and noninvasive BP. Although noise reduction in the PPG is an active field of study, sophisticated techniques of signal reconstruction during movement have focused on accurate estimations of heart rate [39], [40]. PPG motion artifact reduction remains a challenging task.…”

“…Recently, the approach, which is based on signal decomposition [ 22 , 23 , 24 ], demonstrates the best performance among the existing approaches but because its computational load is too heavy, it cannot be applied to the wearable devices requiring real-time processing. Furthermore, the approach presented in [ 24 ] employs the second-order Volterra filter to nonlinearly model motion artifacts with signal decomposition. This shows the possibility on the nonlinear relationship between the motion artifact interference and the acceleration data.…”

“…1). At present, many techniques were proposed to reduce MA from PPG signal during movement, including Wavelet Denoising [8], [9], Independ Component Analysis (ICA) [10], [11], Singular Spectrum Analysis (SSA) [12], [13], Empirical Mode Decomposition (EMD) [14], [15], and [16], Kalman Filtering [17], Adaptive Filtering [18], [19], Particle Filtering [20], [21] and other mixture of methods [22], [23], etc.…”
