METHOD AND APPARATUS FOR SOURCE SEPARATION

An embodiment generally relates to a method of signal discrimination. The method includes receiving plurality of signal mixtures, where each signal has a property whose value is based on a principal eigenvalue of a unique separating operator. The method also includes creating a separating operator using a target signal approximation and applying a separating operator for a target signal to the plurality of signal mixtures. The method further includes obtaining the target signal based on an operation of optimization of the separating operator for maximum property value amplitude on the plurality of signal mixtures.
