%X <p>A new space-time coded transmission scheme is proposed for X channel with two antennas at each user. Each user employs rate-2 space-time block code (R2-STBC). The multi-user interference is eliminated by proper design of transmission method of R2-STBC and pre-coding at the transmitter. The feedback amount is reduced and the transmission efficiency is higher as well, compared with the existing scheme for the same scene. Simulation results demonstrate that the reliability of the proposed scheme significantly outperforms the existing scheme.</p>
