Implementation Issues in Blind Source Separation
Paradoxically, the price for the conciseness of the Sylvester-based notation is its high redundancy. And unfortunately, consistency of this redundant representation of the separation system W is not guaranteed by the algorithms that are given in Chap. 5. For this reason, these algorithms cannot be directly implemented. In the first part of this chapter, our contribution is to propose a systematic and rigorous treatment of this redundancy issue, which eventually provides implementable update rules.
