Abstract

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