A modified Cao method with delay embedded

A modified Cao method has been proposed in this paper, which is a new phase space reconstruction algorithm using multiple delay embedded. Through the proposed method, the minimum embedding dimension and the best time delay could be determined under a unified criterion, so that the applications of Cao method can be expanded. The numeral simulation demonstrates that, compared with the single-delay embedded method used currently, the proposed algorithm has obvious advantages in dealing with the signals which contain multiple strong periodic components.
