An ICA based prediction method for EMI and EMC

This article mainly discusses the evaluation and prediction method for the electromagnetic interference and electromagnetic compatibility of electronic devices or systems. An Independent Component Analysis (ICA) based method is introduced in order to separate or recover source electromagnetic signals and interfering signals from mixed signals. A simulation experiment is also given to demonstrate the validity and feasibility of the proposed method. Finally, a process scheme by combining the ICA based method and system method is proposed, in order to help design and analyze the EMC performance of electronic devices and systems.
