Geometric approach for blind separation of signals
Carlos G. Puntonet, A. Prieto · Electronics Letters · 1997
The authors suggest an approach to resolve the problem of the blind separation of p ≥ 2 sources. At one instant of time the sources and observations are considered as two vectors, and a simple method for estimating the mixing matrix is proposed for a linear medium with bounded sources, where at least one set of orthogonal vectors is generated.
