Based on a new aperiodic homogenous Markov model for presenting digital square modulations of a constant envelope, a new stochastic matrix method for the determination of their spectral correlation has been proposed. Formulae for spectral correlation of M-PSK and 2x2SQAM signals have been derived and, for some types of these signals, theoretical and graphical results of their spectral and correlation characterization based on this method have been given.

Ključne reči:   Spectral correlation, digital square modulations, cyclostationary signals.
