论文摘要
无线电本地化是第五/第六代（5G/6G）通信系统中联合通信和传感的关键推动力。借助多路径组件（MPC），如果两个基本站（BS）（BS）和单同步用户设备（UE）可以完成本地化和映射任务，则它们都配备了天线阵列。但是，UE侧的天线阵列增加了硬件和计算成本，从而阻止了本地化功能。在这项工作中，我们表明，通过多普勒估计和MPC，即使使用单个Antenna Mobile UE，也可以执行本地化和映射任务。此外，我们表明，随着UE速度的提高，本地化和映射性能将改善，然后在一定水平上饱和。理论上的Cramér-Rao结合分析和仿真结果都表明了迁移率下定位的潜力以及所提出的定位算法的有效性。
Radio localization is a key enabler for joint communication and sensing in the fifth/sixth generation (5G/6G) communication systems. With the help of multipath components (MPCs), localization and mapping tasks can be done with a single base station (BS) and single unsynchronized user equipment (UE) if both of them are equipped with an antenna array. However, the antenna array at the UE side increases the hardware and computational cost, preventing localization functionality. In this work, we show that with Doppler estimation and MPCs, localization and mapping tasks can be performed even with a single-antenna mobile UE. Furthermore, we show that the localization and mapping performance will improve and then saturate at a certain level with an increased UE speed. Both theoretical Cramér-Rao bound analysis and simulation results show the potential of localization under mobility and the effectiveness of the proposed localization algorithm.
