The existence of shift for periodically correlated processes and its boundedness are investigated. Spectral criteria for these non-stationary processes to have such shifts are obtained.
آنالیز فرآیندهای ایستا در قلمرو(دامنه طیفی) بر توزیع های طیفی بنا شده است . اما برای فرآیندهای غیرایستای هارمونیک ساز(harmonizable) ، زوج (f, ) که f یک اندازه برداری (vector measure) و یک اندازه بورل می باشد ، به عنوان مشخصه های طیفی ارائه می شود. در این پایان نامه یک روش طبیعی برای ساختن نمایش طیفی ارائه می شود که این روش برای فرآیندهای مرتبه دوم (second order processes) و فرآیندهای پایدار (st...
simple harmonizable processes (shp) introduced by soltani and parvardeh (2006) are a large class of nonstationary processes which includes stationary and periodically correlated (pc) processes. detection and estimation of shp structure are important problems when dealing with nonstationary data. in this paper, we study the spectral properties of simple processes and propose a method to detect a...

in this work we introduce and study discrete time periodically correlated stable processes and multivariate stationary stable processes related to periodic and cyclic flows. our study involves producing a spectral representation and a spectral identification for such processes. we show that the third component of a periodically correlated stable process has a component related to a...
