摘要:

定位预计将在未来无线网络中发挥重要作用,因为定位与态势感知、导航和跟踪是6G使用场景的组成部分。然而,在许多情况下,定位需要额外设备,这会干扰通信系统,同时还需要额外资源。另一方面,高频和高度定向的通信在角度域和距离域提供了新的更高分辨率能力框架。正在探索集成感知与通信的实现方式,以统一感知和通信系统并推动“以通信实现感知”的方法。为此,本文提出一种定位算法,利用波束成形和新兴的波束聚焦技术来估计接收机的位置。该算法可以用大型天线阵列和大型智能表面实现。通过蒙特卡洛仿真评估了该算法对静态和移动用户的性能。结果以静态和移动用户的经验累积分布函数以及静态用户的成功估计概率形式呈现。

英文摘要:

Localization is expected to play a significant role in future wireless networks as positioning and situational awareness, navigation and tracking, are integral parts of 6G usage scenarios. Nevertheless, in many cases localization requires extra equipment, which interferes with communications systems, while also requiring additional resources. On the other hand, high frequency and highly directional communications offer a new framework of improved resolution capabilities in the angular and range domains. The implementation of integrated sensing and communications is being explored to unify the sensing and communications systems and promote a communicate-to-sense approach. To this end, a localization algorithm is presented that utilizes beam-forming and the emerging beam-focusing technique, to estimate the location of the receiver. The algorithm can be implemented with large antenna arrays, and large intelligent surfaces. The performance of the algorithm for static and mobile users is evaluated through Monte-Carlo simulations. The results are presented with the empirical CDF for both static and mobile users, and the probability of successful estimation for static users.
