To investigate the connection between cyclostationary signal properties and spectral correlation, and to explore how spectral redundancy can improve signal detection and estimation.
Analyzed the relationship between periodicities in second-order moments, quadratic nonlinear transformations, and spectral-line generation.
Evaluated the effects of fundamental signal processing operations—including filtering, product modulation, and time sampling—on spectral-correlation characteristics.
Demonstrated that cyclostationarity generates spectral correlation, representing statistical dependence between signal components in distinct frequency bands.
Established analytical formulations to derive spectral-correlation profiles and exploit spectral redundancy for detecting and estimating heavily corrupted man-made signals.
