Abstract
A wavelet domain approach to blind source separation which avoids the permutation problem in transfer domain operation, and yields improved convergence rate for certain non-stationary signals, is introduced. The wavelet transform also facilitates noise reduction, further improving performance of the natural gradient algorithm
