The new digital radio system DAB (Digital Audio Broadcasting), developed within the Eureka 147 project in close cooperation with the EBU, is a very innovative and universal multimedia broadcast system that is just being introduced, and which has the potential to replace existing AM and FM audio broadcast services in many parts of the world in the near future. In several countries in Europe and overseas, broadcasting organisations, network providers and receiver manufacturers are already implementing digital broadcasting services using the DAB system. DAB is very different from conventional analogue broadcasting systems. Most of the system components such as perceptual audio coding (MPEG-1/2), OFDM channel coding and modulation, the provision of a multiplex of several services and data transmission protocols (MOT), are new concepts typical of digital broadcasting. Even experts in analogue transmission systems will feel less familiar with these new elements of broadcasting technology. Therefore, the aim of this book is to inform the expert reader about the basic concepts of the DAB system.
