In this paper, we propose a massive MIMO (multiple-input-multiple-output) architecture with distributed steerable phased antenna subarrays for position estimation in the mmWave range. We also propose localization algorithms and a multistage/multiresolution search strategy that resolve the problem of high side lobes, which is inherent in spatially coherent localization. The proposed system is intended for use in line-of-sight indoor environments. Time synchronization between the transmitter and the receiving system is not required, and the algorithms can also be applied to a multiuser scenario. The simulation results for the line-of-sight-only and specular multipath scenarios show that the localization error is only a small fraction of the carrier wavelength and that it can be achieved under reasonable system parameters including signal-to-noise ratios, antenna number/placement, and subarray apertures. The proposed concept has the potential of significantly improving the capacity and spectral/energy efficiency of future mmWave massive MIMO systems.

基于分布式可控相控天线阵列的毫米波大规模MIMO系统的位置估计。

在本文中，我们提出了一种大规模MIMO（多输入多输出）架构，该架构具有分布式可控相控天线子阵列，用于mmWave范围内的位置估计。我们还提出了定位算法和一种多级/多分辨率搜索策略，可以解决空间相干定位中固有的高旁瓣问题。拟议的系统旨在用于视线室内环境。不需要在发送器和接收系统之间进行时间同步，并且算法也可以应用于多用户方案。仅视线和镜面多径情况的仿真结果表明，定位误差只是载波波长的一小部分，并且可以在合理的系统参数（包括信噪比，天线数量）下实现/位置和子阵列孔径。所提出的概念具有显着提高未来毫米波大规模MIMO系统的容量和频谱/能量效率的潜力。
