摘要

数字音频广播(DAB)系统比现有的调频广播提供更好的服务，预计在不久的将来将得到普及。DAB接收机的一项重要任务是帧同步，它包括检测信号的存在和确定帧的开始。检测方法必须具有鲁棒性，并在任何潜在的信道条件下提供任意低的虚警概率。在本文中，我们提出了一种鲁棒的算法来确定帧的开始，并给出了在模拟条件下的性能结果

A Null Symbol Detection Algorithm for DAB Receivers

Digital audio broadcasting (DAB) systems are expected to gain popularity in the near future as they offer better services compared to existing FM broadcasting. An important task of a DAB receiver is frame synchronization, which involves detecting the presence of a signal and determining the start of the frame. The detection method has to be robust and provide an arbitrarily low probability of false alarm in any potential channel condition. In this paper, we propose a robust algorithm to determine the start of frame and present the performance results in simulated conditions
