A delay partition method for calculating complexity of physiological signals

It is often required to take a partition preprocessing before a complexity analysis is made for biomedical signal time series. Due to noise existing in signal measuring system, a wrong analysis result may be produced, and even the dynamic property of the original signal may be radically distorted in some case. In order to solve such problems, a delay partition method was presented. The proposed method can obtain the reconstructed string objectively representing the original signals. The simulation and electroencephalogram signal complexity analysis have shown that the delay partition method is proper and effective.
