Abstract
A data processing system blind source separation of an overcomplete set of signals generally includes means for storing input from sensors in a mixed signal matrix X, noise in a noise matrix V, an estimate of the individual signals from the mixture of signals from the signal sources in a source signal estimate matrix Ŝ, and an estimate of environmental effects in a mixing matrix Â, the matrices related by X=ÂŜ+V; generating an initial estimate of Â; determining the number of, and associated lines of correlation of, each source from Â, and representing the sources in the source signal estimate matrix Ŝ; jointly optimizing Ŝ and  in an iterative manner to generate an optimized source signal estimate matrix Ŝand a final estimated mixing matrix Â; and restoring the separated source signals from the optimized source signal estimate matrix Ŝ
