摘要/Abstract

摘要：

为了消除两用户的多输入多输出多址接入信道(MIMO-MAC)中用户间的干扰,提出了一种基于有限反馈的空时码传输方案. 每个用户采用基于相位旋转的速率为2的空时码,每个码字自身需要一个反馈角度,对接收信号进行简单相加后可消除多用户干扰,实现全分集. 与MIMO-MAC中已有的基于有限反馈的空时码传输方案相比,所提方案增大了接收端的信噪比,提高了系统的可靠性.

关键词: 多输入多输出, 多址接入信道, 空时码, 多用户干扰, 有限反馈

Abstract:

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.

Key words: multi-input multi-output, multiple access channels, space-time code, multi-user interference, limited feedback
