A Simple Statistical Analysis of Wavelet-based Multifractal Spectrum Estimation
The multifractal spectrum characterizes the scaling and singularity structures of signals and proves useful in numerous applications, from network traffic analysis to turbulence. Of great concern is the estimation of the ...
Pseudo Affine Wigner Distributions: Definition and Kernel Formulation
In this paper, we introduce a new set of tools for time-varying spectral analysis: the pseudo affine Wigner distributions. Based on the affine Wigner distributions of J. and P. Bertrand, these new time-scale distributions ...
