摘要：
Multiwavelets offer symmetry, orthogonality, and short support, which is not possible with scalar wavelet. In this paper, we analyzed chaotic time series using multiwavelets. Two benchmark chaotic time series and the real-world data of Sunspots time series were analyzed. Three type of accuracy criteria: Mean square error, Root mean square error and Mean absolute error were used to measure the performance of the reconstruction. And the results were compared to the scalar wavelet. Experimental results indicate that multiwavelets were superior to scalar wavelet for chaotic time series analysis.
