论文摘要
随着对基于位置服务的需求不断增长，本地化技术研究最近加剧了。接收到的信号强度（RSS）的定位具有简单性的优势。但是，由于基于RSS的本地化需要路径损失模型参数，因此很难将这些参数未知的位置使用。在先前的研究中，提出了具有多个固定接收器的发射器定位算法，以在未知路径指数（PLE）条件下使用。但是，如果使用移动接收器，则仅使用一个接收器就可以进行本地化。在本文中，我们建议一种基于RSS的LTE基站（BS）定位的方法，当PLE未知时，单个移动接收器。我们还提出了一种有效的移动接收者运动方法，以提高PLE估计和BS定位精度。仿真结果证明了所提出的方法的性能。
With the increasing demand for location-based services, localization technology research has recently intensified. Received signal strength (RSS)-based localization has the advantage of simplicity. However, as RSS-based localization requires the path-loss model parameters, it is difficult to use in place on which those parameters are unknown. In prior research, a transmitter localization algorithm with multiple stationary receivers was proposed for use under unknown path-loss exponent (PLE) conditions. However, if a mobile receiver is utilized, the localization would be possible with a single receiver alone. In this paper, we suggest a method of RSS-based LTE base station (BS) localization with a single mobile receiver when the PLE is unknown. We also propose an efficient mobile-receiver movement method to improve the PLE estimation and BS localization accuracy. Simulation results demonstrate the performance of the proposed methods.
