Blind separation of surface EMG signals

Multiple site measurements with surface EMG elctrodes can produce a significant amount of cross-talk, which depends on electrode placement. The "blind separation" techniques can be used to reduce that cross-talk. However the conventional techniques are not very effective if the media causes latencies in signal propagation, which is the case of myoelectric potentials. The algorithm proposed here takes into account the latencies of the media and uses FIR decorrelators which significantly reduce the unwanted cross-talk.
