Abstract EN
A B-spline empirical mode decomposition (BEMD) method is proposed to improve the celebrated empirical mode decomposition (EMD) method.
The improvement of BEMD on EMD mainly concentrates on the sifting process.
First, instead of the curve that resulted from computing the average of upper and lower envelopes, the curve interpolated by the midpoints of local maximal and minimal points is used as the mean curve, which can reduce the cost of computation.
Second, the cubic spline interpolation is replaced with cubic B-spline interpolation on account of the advantages of B-spline over polynomial spline.
The effectiveness of BEMD compared with EMD is validated by numerical simulations and an application to find the basis functions of EMI signals.
