The analysis of the complex electromagnetic environment based on the independent component analysis

Under the complex electromagnetic environment, it is always difficult to analyze the electromagnetic compatibility and determine the deployment of the electromagnetic signal sources, when only the mixed signals can be obtained. In this paper, we focus on the analysis of the complex electromagnetic environment with signal sources unknown. We first present some results on the ICA method and the confidence interval. Then, based on these results, we implement a simulation experiment by separating estimated independent component signals from the mixed source signals. The simulation results show that the application of the ICA method to the analysis of the complex electromagnetic environment is valid and efficient.
