Extract Signals of Power Line Communication by a Novel Method Based on EMD and ICA
Hong Li · Proceedings of the CSEE · 2007
In this paper,a novel method to gain communication signals from the power line which based on empirical mode decomposition (EMD) and independent component analysis (ICA) is presented. Gain a set of the intrinsic mode function (IMF) by using EMD to decompose the voltage signals which had been acquired from the power line. Secondly,seek those IMFs whose have the minimum correlative coefficient. Deal with those IMFs and the voltage signals using ICA,and can obtain a lot of independent component. So the communication signals are pick-up. The method integrates the virtue of EMD and ICA and overcome the lack of ICA which cannot decompose single signal. Simulation results reveal that the proposed the method of EMD and ICA can effectively decompose mixed signals,can precisely extract communication signals of the power line communication.
