%X The Alamouti space-time block code provides full transmit diversity and full code rate for systems with two transmit antennas. In this paper, an orthogonal-constellation modulation (OCM) is proposed, which is based on the complex signal constellation of Alamouti scheme. The code rate of OCM is two. The code rate of OCM is two times that of BPSK Alamouti scheme. Simulation results show that the performances of power normalized OCM is equivalent to that of BPSK Alamouti scheme and better than QPSK Alamouti scheme's.
