An improved space-time coded transmission scheme with limited feedback is proposed in order to eliminate interference for two-user multi-input multi-output multiple access channels (MIMO-MAC). Each user employs rate-2 space-time block code with phase rotation, which requires a phase feedback. The multiuser interference is eliminated through simple addition of the received signal, and full diversity is realized. The signal to noise ratio is increased in the proposed scheme and the system performance is improved compared with the existing space-time coded transmission scheme with limited feedback.
