The structure of predictable discrete-time cyclostationary processes
Giancarlo Ferrari‐Trecate, Giuseppe De Nicolao · Infoscience (Ecole Polytechnique Fédérale de Lausanne) · 1998
The Wold decomposition of discrete-time CS (cyclostationary) processes into regular and predictable component is considered. Using the properties of the zeros of linear periodic systems it is shown that the predictable component consists of a linear combination of sinusoidally modulated periodic waves.
