"Linear Prediction Based Blind Source Extraction Algorithms in Practical Applications"
by Zhi-Lin Zhang, Liqing Zhang
in the Proceedings of the 7th International Conference on Independent Component Analysis and Blind Signal Separation (ICA 2007), 2007, pp. 309-316
As we see, blind source extraction (BSE) is advantageous over blind source separation (BSS) when obtaining some underlying source signals from high dimensional signals. Among a variety of BSE algorithms, a large number of algorithms are based on linear prediction (LP-BSE). In this paper we reveal that they are, in nature, minor component analysis (MCA) algorithms, and thus they have some problems that are inherent in MCA algorithms. We also find a switch phenomenon of online LP-BSE algorithms, showing that different parts of a singly extracted signal are the counterparts of different source signals. The two issues should be noticed when one applies these algorithms to practical applications. Computer simulations are given to co- nfirm these observations.
