摘要
电子元器件的噪声,通信网络中的数据流量等信号具有分形特性,分形维数是此类信号分形特性的量度。文中研究了基于分形布朗运动模型的分形维数估计的不同方法,对于此类信号的仿真及分类提供了有效方法。
Fractal signal widely exists in all kinds of natural phenomena. Fractal dimension present the fractal characteristics of this kind of signal. This paper investigates and compares two methods of estimating fractal dimension of signal based on fractal Brownian motion.
