Abstract
We address the problem of blind source separation in the case of a time-dep
endent mixture matrix. For a slowly and smoothly varying mixture matrix, we
propose a systematic expansion which leads to a practical algebraic soluti
on when stationary and ergodic properties hold for the sources. (C) 2000 El
