The natural gradient algorithm is a very important approach for blind source separation (BSS). The aim of this paper is to investigate the blind source separation of a linear mixture of independent sources of different magnitudes by using the natural gradient algorithm. We compare various activation functions for the algorithm and propose a better one. Simulation results with ten communication signals of different magnitudes show that the algorithm with proposed activation function converges faster than other activation functions.
