Design and Performance Evaluation of Advanced Digital Audio Broadcasting System

DAB is a traditional digital radio broadcasting technology. To enhance the performance and quality of DAB system, DAB+ is standardized with outer coding and superior audio codec (HE-AACv2). Recently, as audio codec technology develops, state of the art audio codec, USAC has been standardized. This paper designs the DAB+ system with USAC to enhance the audio quality and efficiency. USAC can improve the audio quality and efficiency of the digital radio system better than HE-AACv2. This paper describes the design and implementation of digital audio broadcasting system with USAC audio codec based on DAB+ system.
