This text provides a technical review of digital radio system DAB (Digital Audio Broadcasting), a new multimedia broadcast system which will soon replace existing AM and FM audio broadcast services in many parts of the world. Articles by several international experts cover the basic concepts of DAB (audio processing, data transmission, modulation schemes, and how the system can be implemented and operated); new broadcasting components (e.g. perceptual audio coding, OFDM channel coding and modulation); the practical implications for service provision and coverage planning; and the new infrastructure required in studios and broadcasting houses for multiplex and network management. Written for broadcasting engineers and technical operators, content providers and programmers, and broadcast students.
