In this paper, we consider the problem of separating a set of
independent components when only one movable sensor is
available to record the mixtures. We propose to exploit the
quasi-periodicity of the heart signals to transform the signal
from this one moving sensor, into a set of measurements, as if
from a virtual array of sensors. We then use ICA to perform
source separation. We show that this technique can be applied
to heart sounds and to electrocardiograms.
