The effect of signal non-stationarity on the performance of information-maximisation-based blind separation
M.J.T. Alphey, David I. Laurenson, Alan F. Murray · 2002
This paper examines the performance of a blind signal separation system that uses information maximisation techniques, when applied to signals with non-stationary characteristics. It assesses the effectiveness of different methods of removing or reducing the degree of non-stationarity of the source signals, in terms of the level of separation achieved after a fixed training period.
