I don't understand the usefulness of the 90 degree phase shifts in the QS Matrix system, the Scheiber Matrix provides the same "3dB all around" channel separation as QS.
It would be much easier to make an encoder (and decoder) that only uses phase reversals and a Variomatrix type decoder could be developed to dynamically enhance Scheiber Matrix channel separation.
