Abstract


A coherence function characterizing the correlation between harmonic components of two signals that are described by periodically correlated random processes has been proposed. Such function is shown to be invariant with regard to linear transformations of signals. A formula for coherence function is concretized for the amplitude- and phase-modulated signals.

Keywords


periodically nonstationary random process; harmonic correlation; coherence function; linear transformations
