Abstract
We consider the separation of sources when only one
movable sensor is available to record a set of mixtures at distinct
locations. A single mixture signal is acquired, which is firstly
segmented. Then, based on the assumption that the underlying
sources are temporally periodic, we align the resulting signals and
form a measurement vector on which source separation can be
performed. We demonstrate that this approach can successfully
recover the original sources both when working with simulated
data, and for a real problem of heart sound separation.
