Abstract

This paper gives an introduction to a generic OFDM based testbed for positioning using time difference of arrival (TDoA) measurements. An overview of the transmitter system and receiver system is given. Furthermore an inital access algorithm with interference mitigation for subsample delay estimation is presented and simulation results are shown. The influence of the geographic base station mapping and the used synchronization codes is discussed. First measurement results reveal perliminary figures for the expected performance leading to further algorithm investigations.
一种基于OFDM的通用TDoA定位试验台,并对子样本延迟估计进行了干扰抑制
介绍了一种基于正交频分复用技术的TDoA定位测试平台。对发射系统和接收系统进行了概述。在此基础上,提出了一种具有干扰抑制的初始接入算法,并给出了仿真结果。讨论了地理基站映射和使用的同步码的影响。首先测量结果揭示了预期性能的初步数字,从而导致进一步的算法研究。
