本书由北京交通大学和中兴通讯相关研究团队成员合作编写，兼具学术性和工程性的特点。本书阐述了多天线（Multiple-Input Multiple-Output，MIMO）技术的基本概念和未来发展方向，从基础理论、关键技术、工程问题等方面阐述了面向 5G-Advanced 和 6G 的大规模 MIMO（Massive MIMO）、去蜂窝大规模 MIMO（Cell-Free Massive MIMO）和智能超表面（Reconfigurable Intelligent Surface，RIS）技术。 本书深入浅出、概念清晰，可作为去蜂窝大规模 MIMO 及 RIS 技术研究人员的参考资料，也可以作为 6G 研究同行的技术指导资料，还可以作为对 6G 感兴趣读者的技术读物以及高年级硕士生和博士生的学习资料，并为未来 6G 商用的技术选择和决策提供参考。
