ABSTRACT:
A wireless system (e.g., Bluetooth, WCDMA, etc.) with multiple antenna communication channel eigenvector weighted transmissions including possibly differing order symbol constellations for differing eigenvectors. Comparison of maximizations of minimum received symbol distances provides for selection of eigenvector combinations and symbol constellations.
