摘要

精确的超宽带(UWB)测距和定位要求精确估计到达时间(TOA)。本文提出了一种计算效率高的超宽带信号TOA估计算法。该算法首先采用传播算子法(PM)获得传播算子算子，然后采用ESPRIT方法直接估计TOA。与PM相比，该算法不需要进行峰值搜索，与ESPRIT相比，该算法减少了特征分解计算次数，复杂度低，计算效率高，性能接近ESPRIT。仿真结果验证了该算法的有效性。

Computationally efficient TOA estimation for UWB signal

Precision ultra-wideband (UWB) ranging and positioning require accurate estimation of time of arrival (TOA). In this paper, we proposed a computationally efficient algorithm to estimate the TOA for UWB signal. In the algorithm we first obtain the propagator operator by using the Propagator Method (PM), and then we adopt the ESPRIT Method estimating the TOA directly. This algorithm requires no peak searching compared to PM, and reduces the number of eigen-decomposition calculation times compared to ESPRIT, which is low complexity and computationally efficient, and the performance is close to ESPRIT. The simulation results validate the proposed algorithm.
