Abstract

Abstract: 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.

Key words: chaotic map, pattern, symbolic spectrum

摘要： 针对待测时间序列是来自周期信号源、混沌信号源还是随机信号源的问题，提出一种用符号谱定性判定的方法。先对时间序列量化，然后进行编码，继而绘其符号谱。通过对不同类型时间序列的符号谱的对比分析表明，符号谱比K-S熵和功率谱等其他方法更能简单有效地判定时间序列的确定性来源和模式类型。
