Abstract
In this letter, we introduce two matrix-signal constellations for differential unitary space time modulation. We also derive an approximation of the upper bound on the symbol error probability. The new constellations generalize several previously reported constellations and yield better performance when the number of transmitter antennas and the constellation size increase
