Research on identifying pattern of chaotic series with symbolic analysis
Liu Xiong-ying · Computer Engineering and Applications Journal · 2009
In view of whether the time series comes from periodic,chaotic or random source,a qualitative method with symbolic spectrum is proposed.In this method,the time series is quantized firstly,then is coded and its symbolic spectrum is plotted.Several symbolic spectrums of different type of time series show that,symbolic spectrum can identify the deterministic source and pattern of time series simply and efficiently,better than K-S entropy and power spectrum.
