在这封信中，提出了一种用于超宽带信号到达时间估计的归一化阈值选择技术。它利用接收信号样本的峰度。通过模拟研究峰度和最佳归一化阈值之间的依赖性。所提出的技术产生有效的阈值选择，具有较低的复杂性和采样率要求，并且考虑了信噪比和各个通道实现的统计。
In this letter, a normalized threshold selection technique for time of arrival estimation of ultra-wideband signals is proposed. It exploits the kurtosis of the received signal samples. The dependency between the kurtosis and optimal normalized threshold are investigated via simulations. The proposed technique yields efficient threshold selection, has low complexity and sampling rate requirements, and accounts both the signal to noise ratio and the statistics of individual channel realizations.
