Abstract

Long Term Evolution (LTE) networks are rapidly deploying around the world, covering the needs of high data rates demanded by many applications. Still, less attention is paid on the positioning capabilities specified in the LTE standard. Thus, an experimental LTE positioning receiver is presented to assess the positioning accuracy in commercial LTE deployments. This receiver is based on a software defined radio (SDR) and a low-cost radio-frequency (RF) front-end, such as the universal software radio peripheral (USRP) or a DVB-T dongle with the Realtek RTL2832U chipset. These two platforms are then used to capture and post-process real LTE signals generated in the laboratory. The positioning results obtained show the viability on the use of this experimental SDR LTE positioning receiver with low-cost hardware platforms for commercial LTE networks.

LTE真实信号定位与低成本硬件平台的对比结果分析

长期演进(LTE)网络正在全球范围内迅速部署，满足了许多应用对高数据速率的需求。然而，人们对LTE标准中规定的定位能力关注较少。因此，提出了一种实验性LTE定位接收器，以评估商用LTE部署中的定位精度。该接收器基于软件定义无线电(SDR)和低成本射频(RF)前端，例如通用软件无线电外设(USRP)或带有Realtek RTL2832U芯片组的DVB-T加密狗。然后使用这两个平台捕获和后处理实验室中产生的真实LTE信号。实验结果表明，基于低成本硬件平台的试验性SDR LTE定位接收机应用于商用LTE网络是可行的。
