Stable analysis of Fast Independent Vector Analysis algorithm

The Fast Independent Vector Analysis (FastIVA) algorithm [1] is an effective approach to achieve the joint blind source separation (JBSS) problem. However, the authors in [1] do not give the stable analysis for the FastIVA algorithm. In this paper, we extend the work of Intae Lee et al [1] by deriving conditions for local stability for the more general case of noncircular sources. Simulations demonstrate the correctness of our stability analysis.
