The spectral correlation theory of cyclostationary time-series

摘要: Abstract A spectral correlation theory for cyclostationary time-series is introduced. It established that a if and only there exists quadratic time-invariant transformation generates lines, this so the exhibits correlation. Fundamental properties of characterizing function are developed. These include effects periodic modulation periodically time-variant linear filtering. Relationships between radar ambiguity Wigner-Ville distribution explained. The Rice's representation bandpass derived. generalization Wiener relation from density to developed, generalizations aliasing formula time-sampling, frequency conversion amplitude modulation,
