本文的目的是强调超宽带(UWB)通信系统中定时捕获问题的重要性，并讨论该问题的有效解决方案。我们讨论了UWB通信系统的特点，如它们的宽带宽和低发射功率限制，如何使得UWB信号的捕获成为一项困难的任务。并对当前超宽带信号捕获方法进行了综述。此外，我们还讨论了UWB信号捕获中的一些问题和挑战，这些问题和挑战在现有文献中可能没有得到足够的重视。
The goal of this paper is to highlight the significance of the timing acquisition problem in ultra-wideband (UWB) communication systems and discuss efficient solutions to the problem. We discuss how the distinguishing features of UWB communication systems, such as their wide bandwidth and low transmission power constraints, are responsible for making the acquisition of UWB signals a difficult task. A survey of the current approaches to UWB signal acquisition is also given. In addition, we discuss some of the issues and challenges in UWB signal acquisition which may not have received sufficient attention in existing literature.
