基于大规模MIMO基本架构,探讨了信道建模和系统性能分析、信道状态信息获取技术、多用户上下行无线传输技术等大规模MIMO传输关键技术;认为利用大规模阵列天线的多用户多输入多输出(MIMO)传输,将显著提升无线通信系统的频谱效率及功率效率。
Abstract：This paper gives an overview of key techniques in massive MIMO wireless communication. We discuss channel modeling, transmission analysis, channel-state information acquisition, and multiuser uplink/downlink transmission. Multiuser MIMO transmission using a large-scale antenna array can significantly improve spectral efficiency and energy efficiency in a wireless communication system.
