Abstract
the parameter selection problem of permutation entropy (PE) in Logistic chaotic time series is discussed in this paper. The length of window?embedding dimension and time delay- are the three factors influenced the PE , it is discussed the influence accused by only one factor through simulations, and results show that when the value of window length is bigger than some point, the different of PE value is not obvious, meanwhile embedding dimension during 3-5 and delay time equal to 3 or 5. Then, it is discussed that the combined selection of both embedding dimension and time delay, conclusion is that the PE curve can best reflects the changes of status for Logistic Chaotic Series.
