Abstract
In this correspondence, we derive a new cost function that is more general than our previous one and is based on the cross-cumulant (2 x 2) of the out put signals. However, the new algorithm deals with multiple inputs and mult iple outputs (MIMO's) and uses a Levenberg-Marquardt method for the minimiz ation of the cost function.
