混沌混合信号欠定盲分离方法的研究
Research of Undedetermined Blind Source Separation Method on Chaotic Signal
摘要
Abstract
This paper presents an undedetermined blind source separation method for the chaotic mixedsignal.First, the characteristics of chaotic signals were discussed and the independent sun-band functions were gained by using EMD to stratify on the signal.Then the bhnd separation for the chaotic mixed-signal is realized by putting the independent sun-band functions into the single-channel chaotic signal.Finally,the validity and the feasibility of this method were confirmed through the separation experiment on the chaotic signal.The proposed method in this paper can be used to test the system or determine whether chaos was produced in the circuit, and then take corresponding measures to use or inhibit chaos, which is valuable for improving the life of the machine and the stability of the circuit.关键词
