ABSTRACT
In general case, the solution of the blind separation of
sources is based on a cost function, which may be a contrast
function, or a polynomial function of laugher
order statistics. In this paper, we propose
a simpler cost function, based on 4th-order crosscumulants
can be used for the separation of N sources
frown N mixtures instantaneous as well as convolutive,
provided than sources have the same sign of kurtosis.
