[ENY-THESIS-2008-001]
I argue in my dissertation that the use of modern high-resolution spectrum estimation methods, such as Min-Norm, Wigner-Ville distribution and combination of these with higher-order statistics (cumulants), provide more possibilities of analysis of highly distorted electrical signals than known methods of spectrum estimation based on Fourier transform.
