摘要
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。
A short-time fractal dimension concept for complex time-series is given and then a new filter method is put forward, which is called fuzzy control filter method based on short-time rfactal dimension. The simulation results show that this kind of method can be applied to complex signal filter because of its good filter effect.
