Discrete Estimations of Cross-Correlation Components of Periodically Correlated Random Signals

摘要

Properties of cross-correlation components estimations of two periodically correlated random signals are analyzed. The conditions of absence of the first and the second genus aliasing effects are obtained. The formulas for estimations variance which allow to select a valid sampling step in dependences on realization length and signal properties are derived. The results are concretized for amplitude modulated signals.
