摘要
信号滤波是信息科学中的基础性技术之一,在通讯、国防等众多领域有着广泛的应用.本文通过分形维数的计算给出了一种自适应分形滤波方法.实验仿真证明这种方法能有效地去除信号中的噪声.
Signal filtering is a basic technology in information science ,and widely used in many scientific field such as communication , national defence,etc. In this paper, we obtained a kind of adaptive fractal filtering method by calculation of fractal dimension. Simulation proves that the performance of denoising is excellent.
