Claim 18:
19. The apparatus of claim 1, wherein the processing circuitry further configured to:
maximize a measure of non-Gaussianity by optimizing weight vectors:

wopt=arg max E{|G(wHY)|2}

over a predetermined set of observations of an observed signal stream, where:

YN×T=HSN×T+n 

in which Y is the observed signal stream, H is a channel matrix, S is a set of all received signal streams, including both desired signal streams and interfering signal streams, n is noise, and E{x} is expectation of x,
after initialization of a weight matrix W containing the weight vectors, by
iterating, for each row wi∈W, until convergence:

wij+1=−E{G*(z)G*(z)Y}+E{G′(z)G′*(z)}wij+E(yyT)E{G*(z)G″(z)}wij* 

and orthonormalizing the rows to get a unitary W.
