Noisy signal filtration using complex wavelet basis sets
Alauldeen S. Yaseen, Olga Nikolaevna Pavlova, А. Н. Павлов · Technical Physics Letters · 2017
Methods of noisy signal filtration using a discrete wavelet transform (DWT) with real basis sets of the Daubechies family are compared to methods employing a double-density dual-tree complex wavelet transform (DDCWT) with excess (nonorthonormalized) basis sets. Recommendations concerning the choice of filter parameters for minimization of the error of noisy signal filtration are formulated.
