面向5G的大规模MIMO天线阵列研究

摘要

In the large-scale MIMO antenna system,the several UE in station is communicated in same slot and carrier,the space multi-plexing and multiple access is raised and the efficiency of radio load resources,by using large scale antenna bring space free-dom. The reliability and power efficiency of communication in user and station,by using large scale antenna bring diversity gain and array gain. The traditional MIMO antenna designs can’t satisfy space gain and space multiplexing and beam shaping at the same time. Using antenna structure,the beam shaping array is used as the antenna unit of large scale MIMO antenna,space gain and space multiplexing in unit is realized. Using unit array to form beam shaping,al functions of the antenna is gotten in large scale MIMO antenna.%大规模MIMO天线系统中，基站覆盖范围内的多个用户可以在同一时频资源上与基站同时通信，既能充分利用大规模天线配置带来的空间自由度，提高空间复用和多址能力，又能利用大规模天线带来的分集增益和阵列增益，提高用户与基站通信的可靠性和功率效率。传统MIMO天线设计不能同时满足空间增益、空间复用和波束赋形应用。采用天线块结构，将波束赋形阵列作为大规模MIMO天线的天线块，在块间实现空间增益和空间复用，利用块中阵列实现波束赋形，可使大规模MIMO天线实现其所具有的所有功能。
