| 摘 要： | 提出一种基于经验模态分解(EMD)对单路混沌信号进行盲源分离的方法.首先讨论了混沌信号的特征,利用EMD对信号进行分层并且得到独立子波函数,然后把独立子波函数加入到单路混合信号中,从而实现混沌信号的盲分离;最后通过混沌信号的分离实验,证明了本方法的有效性和可靠性.

| Abstract: | In this paper,a method of blind source separation for single-channel chaotic signal based on Empirical Mode Decomposition(EMD) had been presented.The paper discussed the characteristics of chaotic signals and used EMD to stratify on the signal and gain the independent sub-band functions,which was then put into the single-channel mixed signal and the blind separation of the chaotic signal was realized.Finally through the separation experiment of the chaotic signal,validity and feasibility of this method was ... |
