本文基于分形理论中的分数维概念，结出了复杂时间序列的短时分形维数概念，提出了一种新的滤波方法即基于短时分形维数的模糊控制滤波方法。仿真结果表明，该方法滤波效果良好，可应用于复杂信号的滤波。
Based on the concept of fractal in fractal theory, this paper concludes the concept of short-time fractal dimension in complex time series and proposes a new filtering method based on short-time fractal dimension. The simulation results show that this method has a good filtering effect and can be applied to the filtering of complex signals.
