论文摘要
在本文中，我们提出了一个固定的MMWave多用户多输入多输出（MIMO）系统，用于使用唯一的体系结构进行固定的无线访问。数字MIMO系统与模拟多光束天线阵列结合使用，该天线阵列使用高维16x16 Butler矩阵获得16个正交束。提出了该体系结构的系统模型，并用于模拟其性能，并与普通补丁天线的性能相比。考虑了几种MIMO预编码技术，并将其与基本的模拟波束形成。为了验证这些结果，建立了原型，并执行了专门的测量活动。结果表明，系统模型是一个良好的近似值，并且使用多光束天线阵列是大量用户的补丁天线的良好替代方法。
In this paper, we present a fixed mmWave Multi-User Multiple-Input Multiple-Output (MIMO) system for fixed wireless access with a unique architecture. A digital MIMO system is combined with an analog multi-beam antenna array which uses a high-dimension 16x16 Butler matrix to obtain 16 orthogonal beams. A system model of this architecture is presented and used to simulate its performance comparing to the performance of common-used patch antennas. Several MIMO precoding techniques are considered and compared with basic analog beamforming. To verify these results, a prototype is built and a dedicated measurement campaign is performed. The results show that the system model is a good approximation and that the use of the multi-beam antenna array is a good alternative to patch antennas for a large number of users.
