Abstract
We derive a new cost function that is more general than our previous one and is based on the cross-cumulant (2×2) of the output signals. However, the new algorithm deals with multiple inputs and multiple outputs (MIMOs) and uses a Levenberg-Marquardt method for the minimization of the cost function
