Blind source separation for identifying the changing source number
Xiao Liu · Journal of Xidian University · 2003
Based on the energy eigenvector, a new approach for source number determination is presented by using the Independent Component Analysis (ICA) and the wavelet packet discomposition arithmetic. The energy eigenvector of output components is defined. According to the distance among the output component energy eigenvector the redundance output components can be detected and the number of source can be determined. The effectiveness of the arithmetic presented in this paper is verified through the computer simulation.
