Generalized Spectrograms and t -Wigner Transforms
We consider in this paper Wigner type representations W i g τ depending on a parameter τ ∈ [0,1] as defined in [2].We prove that the Cohen class can be characterized in terms of the convolution of such W i g τ with a tempered distribution.We introduce furthermore a class …
