The Wigner distribution of Gaussian tempered generalized stochastic processes
Patrik Wahlberg · 2025-04-04 · via math.PR updates on arXiv.org

We define the Wigner distribution of a tempered generalized stochastic process that is complex-valued symmetric Gaussian. This gives a time-frequency generalized stochastic process defined on the phase space. We study its covariance and our main result is a formula for the Weyl symbol of the covariance operator, expressed in terms of the Weyl symbol of the covariance operator of the original generalized stochastic process.
