Hi,
I' not sure whether this suits your application, but the mathematical
basis for something like that is described in
"Brown: Multi-Channel Sampling of Low-Pass Signals, IEEE Transactions on
Circuits and Systems, 1982"
Unfortunately my implementation of this (related to SAR signal
processing) is highly specific and barely readable, so there's no point
in sharing it.
Good luck!
