Two practical methods of phase space reconstruction
两种实用的相空间重构方法

In this paper, several prevalent methods of phase space reconstruction are studied and their disadvantages are discussed. Based on the previous work, two practical methods of phase space reconstruction under different conditions are presented and the qualities of reconstruction are analyzed. In simulation, by using wavelet denoising approach, the two methods have good results in phase space reconstruction from noisy signals and the first method is better than the second. But the second method is suitable to solve the engineering problems.
