Title: Covariant Time Frequency Representations Through Unitary Equivalence
Author: Baraniuk, Richard G.
Type: Journal Paper
Keywords: time-frequency representations

Abstract: We propose a straightforward characterization of all quadratic time-frequency representations covariant to an important class of unitary signal transforms (namely, those having two continuous-valued parameters and an underlying group structure). Thanks to a fundamental theorem from the theory of Lie groups, we can describe these representations simply in terms of unitary transformations of the well-known Cohen's and affine classes.
