Query: Optimal Scale Invariant Wigner Spectrum Estimation of Gaussian Locally
  Self-Similar Processes Using Hermite Functions   This paper investigates the mean square error optimal estimation of scale
invariant Wigner spectrum for the class of Gaussian locally self-similar
processes, by the multitaper method. In this method, the spectrum is estimated
as a weighted sum of scale invariant windowed spectrograms. Moreover, it is
shown that the optimal multitapers are approximated by the quasi Lamperti
transformation of Hermite functions, which is computationally more efficient.
Finally, the performance and accuracy of the estimation is studied via
simulation.
