中文摘要:

那个 non-line-of-sight (NLOS ) 错误是在到达(TOA ) 的时间阻碍精确性的改进的主要因素,是众所周知的评价并且无线的放。这篇文章建议有效地在 60% 减少 NLOS 错误的 TOA 评价的一个新奇方法,与传统的预定和同步方法作比较。由构造直角的训练序列,这个方法多在 NLOS 把传统的 TOA 评价变换成第一条到达路径(FAP ) 的察觉路径环境,然后估计由双程的传播(RTT ) 的 TOA 技术。理论分析和数字模拟证明在这篇文章建议的方法比传统的方法完成更好的性能。

英文摘要:

It is well known that non-line-of-sight (NLOS) error has been the major factor impeding the enhancement of accuracy for time of arrival (TOA) estimation and wireless positioning. This article proposes a novel method of TOA estimation effectively reducing the NLOS error by 60%, comparing with the traditional timing and synchronization method. By constructing the orthogonal training sequences, this method converts the traditional TOA estimation to the detection of the first arrival path (FAP) in the NLOS multipath environment, and then estimates the TOA by the round-trip transmission (RTT) technology. Both theoretical analysis and numerical simulations prove that the method proposed in this article achieves better performance than the traditional methods.
