摘要：

研究了莱斯信道条件下多对双向大规模多输入多输出放大转发中继系统.多对单天线用户通过配置有大规模天线阵列的中继实现用户对内的信息交换，并对其性能进行分析.首先给出理想和非理想信道状态信息条件下中继处的迫零发送/迫零接收处理矩阵.然后分别得到这两种情况下的渐近信干噪比表达式.最后给出了当中继天线数趋近于无穷大时一般功率分配方案下的渐近频谱效率，并通过蒙特卡罗仿真结果验证理论分析的正确性.

Abstract:

This paper investigates a multi-pair two-way massive MIMO amplify-andforward (AF) half-duplex relay system over Rician fading channels, where multiple pairs of users, each equipped with a single antenna, exchange information within pair through a relay with very large number of antennas. Firstly, the paper gives the zero-forcing reception/zero-forcing transmission (ZFR/ZFT) processing matrix under the conditions of perfect and imperfect channel state information (CSI) at the relay. Then, the asymptotic expressions of the end-to-end signal-to-interference-plus-noise ratio are derived. Finally, the asymptotic spectral efciency (SE) at the general power scaling schemes in the case with infnite number of relay antennas are derived and verifed by the Monte-Carlo simulations.

Key words: massive MIMO, multi-pair user, spectral efciency, power scaling, Rician channels
