Time-Frequency Analysis Time-Scale Analysis |
Description: We introduced 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 time-scale distributions support efficient
online operation at the same computational cost as the continuous
wavelet transform. Moreover, they take advantage of the
proportional bandwidth smoothing inherent in the sliding
structure of their implementation to suppress cumbersome
interference components. To formalize their place within the
echelon of the affine class of time-scale distributions, we
extended the definition of this class and introduced other natural
generators. Joint work with: Richard Baraniuk (Rice Univ.) |
