摘要翻译：
L-band数字航空通信系统-1(L-DACS1)是一种新兴的标准，旨在通过将传统的模拟航空通信系统过渡到高性能的数字领域来增强空中交通管理(ATM)。L-DACS1采用了现代高效的正交频分复用(OFDM)调制技术，与现有的航空通信系统相比，实现了更高效、更高的数据速率。然而，OFDM系统的性能对同步误差非常敏感。L-DACS1传输在L波段的航空信道中，具有较大的干扰和多普勒频移，这使得L-DACS的同步变得更加困难。本文提出了一种新的L-DACS1系统同步方法，该方法计算效率高，具有较强的鲁棒性。仿真结果表明，该方法能在一定范围的航空信道中提供精确的符号定时偏移(STO)估计和分数载波频率偏移(CFO)估计。特别地，它能在面对大载波频率偏移时产生优良的同步性能。

英文摘要：
  L-band Digital Aeronautical Communication System type-1 (L-DACS1) is an emerging standard that aims at enhancing air traffic management (ATM) by transitioning the traditional analog aeronautical communication systems to the superior and highly efficient digital domain. L-DACS1 employs modern and efficient orthogonal frequency division multiplexing (OFDM) modulation technique to achieve more efficient and higher data rate in comparison to the existing aeronautical communication systems. However, the performance of OFDM systems is very sensitive to synchronization errors. L-DACS1 transmission is in the L-band aeronautical channels that suffer from large interference and large Doppler shifts, which makes the synchronization for L-DACS more challenging. This paper proposes a novel computationally efficient synchronization method for L-DACS1 systems that offers robust performance. Through simulation, the proposed method is shown to provide accurate symbol timing offset (STO) estimation as well as fractional carrier frequency offset (CFO) estimation in a range of aeronautical channels. In particular, it can yield excellent synchronization performance in the face of a large carrier frequency offset.
