Abstract: Abstract The statistical characteristics of cyclostationary signals vary periodically in time. In the Gaussian (or second-order) case this property is typically related to the periodic autocovariance function. Thus, many classical methods for detection of cyclostationarity… read more here.

Abstract: This paper explores the asymptotic spectral decomposition of periodically Toeplitz matrices with finite summable elements. As an alternative to polyphase decomposition and other approaches based on Gladyshev representation, the proposed route exploits the Toeplitz structure… read more here.
