The generalized demodulation method based on maximal overlap discrete wavelet packet transform (MODWPT) is well suitable for separating multi-component signals due to the properties of MODWPT such as decomposing a signal into a sum of components and the same time-resolution in all decomposition layers. However, the related separation-method research meets lots of challenges because of multi-component...
This paper proposes a time–frequency (t–f) image enhancement method for suppressing interference terms in the Wigner–Ville distribution. The proposed technique adapts the direction of the smoothing kernel locally at each t–f point, so that the smoothing kernel remains aligned with the ridges of the auto-terms. This local alignment of the smoothing kernel reduces cross-terms without degrading the energy...
