Abstract :
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
