T1 Two-Dimensional Cumulant Functions of Phase-Modulated Signals and their Spectra JF Telecommunications and Radio Engineering JO TRE YR 1999 FD 1999-10-01 VO 53 IS 9-10 SP 23 OP 30 AB Correlation functions and power spectra of high-frequency, modulated signals often fail to provide sufficient information for the analysis of non-linear transformations of such signals. More information about the signals, contained in higher-order moment and cumulant functions, may also be required for the analysis and synthesis of non-linear systems of signal processing in a non-Gaussian noise background. Higher-order moment functions of phase-modulated discrete signals were considered in paper [1]. The present paper is aimed at studying continuous signals. The technique applied for solving the problem allows deriving expressions in a form convenient for practical applications.
