Research on Noise Modeling Method in Power Line Channel System
There are problems of complicated channel environment and complex noise characteristics in the aircraft cable system, which has caused great interference to the normal communication and fault detection of the system. In this paper, based on the classification of typical power line channel noise and its different characteristics, an arc noise modeling method based on fractional-order filter is proposed, and the parameter determination method of arc noise model based on data-driven is proposed, that combined with the typical power line noise, building a more complete and accurate power line channel system noise model. The accuracy of the model is verified by the simulation and experimental results, which can provide a reference for the further study of the power line fault diagnosis technology.
