Blind Source Separation and Beamformaing: Algebraic Technique Analysis.

Blind source separation (BSS) and blind beamforming schemes attempt to separte additive source signals, collected at a sensor array, and their direction-of-arrival (DOA). To this extent, many different and powerful algorithms have been produced to accomplish these tasks. However, unlike an optimal or adaptive method, an algebraic method for BSS and blind beamforming has the relative advantage of simplicity. This paper investigates such technique that provides closed-form, algebraic expression for BSS and beamforming in terms of performance and reliability. We provide these results, as well as a summary of the properties, and possible uses for this technique, in contrast to more optimal, adaptive techniques. [ABSTRACT FROM AUTHOR]
