Abstract :
This paper proposes a quasi-orthogonal space-time-frequency block coding scheme (QOSTFBC) based zero multi-user interference beamforming in a MIMO-OFDM system. It achieves multiuser communication, and effectively eliminates multi-user interference. At the same time, it takes advantage of the linear constellation precoding (LCP) to ensure that the systems obtain full rate and full diversity gain.
