【摘要】：通过对Logistic映射序列和采集的针灸刺激HRV(heart rate variability)信号叠加不同的趋势,探究基本尺度熵和近似熵的稳定性。结果表明:对于具有不同趋势的Logistic映射序列和心率变异性信号(针灸刺激信号),近似熵非常敏感,不能准确区别趋势中的不同信号,不适用于分析具有趋势的信号;而基本尺度熵在不同趋势下表现出较好的稳定性和准确性,该方法可广泛应用于实际信号的分析。
[Abstract]:The stability of basic scale entropy and approximate entropy was explored by superposing different trends of Logistic mapping sequence and acupuncture stimulation HRV (heart rate variability) signal. The results show that the approximate entropy is very sensitive to the Logistic mapping sequence and the heart rate variability signal (acupuncture stimulation signal) with different trends, and it is not suitable for the analysis of the signals with the trend. The basic scale entropy shows good stability and accuracy under different trends. This method can be widely used in the analysis of practical signals.
