| Abstract: | Higher-order almost cycloststionary complex processes are complex random signals with almost periodically time-varying statistics, which is important to the research of non-Gaussian signals in information system. In this paper, smoothed polyperiodograms are proposed for related to cyclic polyspectral estimation and are shown to be consistent and asymptotically complex normal. Asymptotic covariance expressions are derived along with their computable forms. |

| Keywords: | Complex cyclostationary sequences Nonparametric cyclic-polyspectrum estimation Asymptotic statistical performance |
