Positive time-frequency distributions based on joint marginal constraints

This correspondence studies the formulation of members of the Cohen-Posch class of positive time-frequency energy distributions. Minimization of cross-entropy measures with respect to different priors and the case of no prior or maximum entropy were considered. It is concluded that, in general, the information provided by the classical marginal constraints is very limited, and thus, the final d...

A note on "Positive time-frequency distributions"

—We discuss the performance of certain recently proposed positive time-frequency distribution functions with correct marginals. It turns out that for signals of the FM type, satisfactory results can only be obtained with a strongly signal dependent choice of the param eters in these distribution functions.

Construction of positive time-frequency distributions

AbstructA general method for constructing nonnegativedefinite, joint time-frequency distributions (TFD’s) satisfying the marginals of time Is(t)l ’ and frequency lS(f)12 is presented. As nonnegative-definite distributions with the correct marginals, these TFD’s are members of the Cohen-Posch class. Several examples illustrating properties of these TFD’s are presented for both synthetic and real...

Automatic Classification of Positive Time- Frequency Distributions

A method of performing automatic classification of positive time-frequency distributions is presented. These distributions are computed via constrained optimization, minimizing the cross-entropy of the distribution subject to a set of constraints. An algorithm for clustering using cross-entropy as the distance measure between vectors was derived by Shore and Gray [14]. We apply this method to t...

Time- Frequency Distributions Based on Conjugate Operators*

New classes of quadratic time-frequency representations (QTFRs), such as the affine, hyperbolic, and power classes, are interesting alternatives to the conventional shift-covariant class (Cohen's class). This paper studies new QTFR classes that retain the inner structure of Cohen's class. These classes are based on a pair of "conjugate" unitary operators and satisfy covariance and marginal prop...
