Asymptotic distribution for periodograms of infinite dimensional discrete time periodically correlated processes. (English) Zbl 1244.60038
From the abstract: “In this article, we shall consider a class of strongly \(T\)-periodically correlated processes with values in a separable complex Hilbert space H. The periodograms of these processes and their statistical properties were previously studied by the authors. In this paper, we derive the asymptotic distribution of the periodogram that appears to be a certain Wishart distribution on H\(^T\).”
