摘要
In this paper we address the problem of on-line source separation with sources modelled as mixtures of Gaussian which are linearly combined via a series of non-stationary mixing matrices. The online recovery of the sources from the observations is a non-linear statistical filtering problem that we propose to address using state of the art particle filter methods. Simulations are presented and satisfactory results are obtained.
