Abstract In phase space reconstruction of time sequences,the selection of embedding dimension is important.Based on the idea of looking at the behavior of enar neighbors under changes in the reconstruction is constructed.This method has asound theoretical basis and can get good result.By the way,it can indicatethe noise level in the data to be reconstructed,and estimate the effect of reconstruction.It is applied to speech signal reconstruction.
