Periodically non-stationary random processes modeling: Approach on the basis of harmonic representation

Theoretical and experimental results of time series modeling are summarized. Special attention is given to periodically correlated random processes (PCRP). It is suggested to use the parametric modeling methods on the basis of PCRP decomposition on stationary processes for construction of the process model. Proposed parametrical model is helpful for veriflcation the efficiency of devices and systems with periodical character of sources.
