| Abstract: | The fractal theory is an effective tool to describe irregular geometry form and structure in nonlinear system and its application is greatly wide. Firstly,describes the idea and basic characteristic of fractal, fractal dimension and familiar estimation methods. Then expatiates on the applications and findings of fractal theory in signal processing such as signal simulation and modeling, target detection in complicated background, fault diagnosis, speech signal processing. Finally,expects future application and progress of fractal theory in signal processing. |
