there are a number of methods of interpolation and not all are equal.
an interpolated channel is the linear combination of 2 or more other real
Hence, a new dimension of data is not being created by doing the
Hence, the interpolated channel does not benefit the ICA process.
it is pemissible to interpolate channels of back-projected (scalp projected)
components "after" applying ICA.
