摘要

本文提出了一种利用多径参数估计算法重构OFDM系统零子载波上信道频率响应的TOA估计方法。采用IEEE 802.11ac标准中定义的传统长训练域对所提出的方法进行了评估，仿真结果表明，在802.11信道模型B和WINNER A1 LOS信道中，当信号带宽为20-40 MHz时，所提出的方法都优于最先进的方法。

A Novel Time-Of-Arrival Estimation Approach with Channel Frequency Response Reconstruction in OFDM systems

This paper presents a novel TOA estimation approach by utilizing multipath parameter estimation algorithm to reconstruct channel frequency response on null subcarriers in OFDM systems. The proposed approach is evaluated using legacy long training field defined in IEEE 802.11ac standard, and is shown by simulations to outperform the state-of-the-arts when signal bandwidth is 20-40 MHz in both 802.11 channel model B and WINNER A1 LOS channel.
