Abstract :
In this letter, a new class of signal constellations is proposed for differential unitary space-time modulation with multiple transmit antennas. In the proposed method, a rotation matrix is introduced to design signal constellations with large diversity product which is a primary property for signal constellations to have good performance in high signal to noise ratio (SNR).
