Statistical analysis of periodically non-stationary oscillations for unknown period

The strict characteristic and the comparative analysis of the developed by authors the coherent and the component methods for statistical analysis of periodically correlated random processes (PCRP) — the mathematical models of the stochastic oscillations — for unknown period of the non-stationarity is given. The comparison of efficiencies of the proposed methods for period estimation with the given in literature for individual cases of PCRP is provided.
