On the Cyclostationary Linear Inverse Models: A Mathematical Insight and Implication
Justin Lien, Yan-Ning Kuo, Hiroyasu Ando
Cyclostationary linear inverse models (CS-LIMs), generalized versions of the classical (stationary) LIM, are advanced data-driven techniques for extracting the first-order time-dep…
