Stability analysis of blind signals separation algorithms

Blind source separation (BSS)/ independent component analysis (ICA) is an emerging research field in both theory and applications. It has been motivated by practical applications that involve multiple source signals and observation sensors and share a common objective, that is to separate source signals and estimate channel parameters without knowing the characteristics of the transmission channel. In this paper, we propose an algorithm, analyze its dynamical behaviors and answer the problem whether the resulting signals are the source signals.
