  • Abstract
    A new power efficient modulation scheme for two transmit antennas is introduced. It is an extension of π/4-DQPSK used in single antenna systems. It achieves full diversity advantage and is suitable for nonlinear amplifiers due to its inherit π/4-phase shift in every symbol interval for both antennas.
