Abstract :
The paper proposed the definition of signal energy change degrees and proved the properties of signal energy change degrees. Based on the new definition and properties, a blind source separation method has been proposed in this paper. The purpose of separated signal has been achieved by using the generalized eigenvalue theory of the matrices, setting the generalized eigenvalue of signal energy change degrees and solving the generalized eigenvalue of eigenvector. Experimental simulations show that the new method is valid, efficient, and easy to implement in practice.
