一种自适应单入多出盲源分离方法
A SELF-ADAPTIVE ALGORITHM FOR SINGLE INPUT MULTIPLE OUT BLIND SOURCE SEPARATION
摘要
Abstract
Single input multiple out blind source separation (SIM0_BSS) is a special kind of underdetermined blind source separation.In the process of existing algorithms,too much personal experience is required in judging,and the self-adaptability is poor.To address this problem,we propose that first the ensemble empirical mode decomposition (EEMD) is used to decompose the single-channel signal which is the mixture of multi-channel signals into multi-channel intrinsic mode functions (IMSs) ; then,the principal component analysis is applied to reduce the dimensionality of multi-channel IMFs adaptively,meanwhile the independent component analysis is used to restore the mutualindependent multiple source signals.Finally,the simulation is conducted on periodic mixed signal and biological mixed signal,the simulation results indicate that the proposed algorithm has quick speed with good separation effect than the EEMD_ICA algorithm under different NSR conditions.关键词
