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