Abstract :
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
