AbstractWe present a theory of quadratic time-frequency (TF) energy distributions that satisfy a covariance property and generalized marginal properties. The theory coincides with the characteristic function method of Cohen and Baraniuk in the special case of "conjugate operators.''
KeywordsTime-frequency representations, conjugate operators, Cohen's class
