  • Measuring Time-Frequency Information and Complexity using the Renyi Entropies 

    Baraniuk, Richard G.; Flandrin, Patrick; Michel, Olivier (1995-09-01)
    In search of a nonparametric indicator of deterministic signal complexity, we link the Renyi entropies to time-frequency representations. The resulting measures show promise in several situations where concepts like the ...
  • Measuring Time-Frequency Information Content using the Renyi Entropies 

    Baraniuk, Richard G.; Flandrin, Patrick; Janssen, A. J. E. M.; Michel, Olivier (2001-05-01)
    The generalized entropies of Renyi inspire new measures for estimating signal information and complexity in the time-frequency plane. When applied to a time-frequency representation (TFR) from Cohen's class or the affine ...
  • Time-Frequency Complexity and Information 

    Flandrin, Patrick; Baraniuk, Richard G.; Michel, Olivier (1994-04-01)
    Many functions have been proposed for estimating signal information content and complexity on the time-frequency plane, including moment-based measures such as the time-bandwidth product and the Shannon and Renyi entropies. ...
  • Time-Frequency Based Distance and Divergence Measures 

    Michel, Olivier; Baraniuk, Richard G. (1994-10-01)
    A study of the phase and amplitude sensitivity of the recently proposed Renyi time-frequency information measure leads to the introduction of a new "Jensen-like" divergence measure. While this quantity promises to be a ...
