Abstract
A linear prediction approach reduces convolutive independent component analysis (ICA) to the following three steps: solution of a set of multivariate linear prediction problems, a linear multivariate deconvolution problem with known matrix coefficients, and finally solution of a conventional instantaneous mixing ICA problem.
