Abstract
Cyclostationary processes are an important class of nonstationary proc esses. In this correspondence we consider nonparametric estimation of the cyclic cross-spectrum. A smoothed periodogram-based estimator is s tudied and its asymptotic behavior characterized, extending recent uni variate work to the multivariate case. Application to cyclic coherence measurements is discussed, The results are useful in a variety of mul tisensor cyclostationary signal processing scenarios such as time dela y and bearing estimation.
