Multichannel blind separation of sources algorithm based on cross-cumulant and the Levenberg-Marquardt method

摘要

We derive a new cost function that is more general than our previous one and is based on the cross-cumulant (2/spl times/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.
