An improved method for signal enhancement based on ICA
Duan Shou-min, E Audio · Audio Engineering · 2003
Reducing additive noise by using independent component analysis(ICA)fr om one noisy signal can be rephrased as the application of ICA under insufficien t observations.The key to the prob-lem is to construct another mixed signal r easonably.This paper provides an improved method for con-structing another mix ed signal.The experiments demonstrate that the performance of the method is sat-isfactory.
