%X <p>New space-time coded transmission scheme was proposed for multiple input multiple output (MIMO) interference channel with three users. Rate-2 space-time codeword was designed for every user. The unwanted codeword for the last two receivers is aligned through interference alignment pre-coding, and then is eliminated through non-linear operations on the received signals. The unwanted codeword for the first receiver is canceled through unidirectional operational link and non-linear operations. Compared with the existing scheme for the same scene, the proposed scheme improves the transmission efficiency, while keeping the same diversity gain. Simulation shows that, with the same transmission rate, the proposed scheme outperforms the existing scheme.</p>
