The application of space diversity for digital audio broadcasting
1988 IEEE 5th International Symposium on Spread Spectrum Techniques and Applications - Proceedings. Spread Technology to Africa (Cat. No.98TH8333), 2002Numerous investigations on the minimum required fieldstrength for digital audio broadcasting (DAB) reception have been made. The maximum symbol error rate (SER) of the unprotected channel which guarantees good signal quality at the receiver output has been determined, too. Consequently, many coverage parameters are already fixed. To improve and enlarge

Cooperative Digital Audio Broadcast Networks
2007 IEEE International Conference on Communications, 2007Digital audio broadcast (DAB) systems are considered for delivery of audio information to users in heavily attended sporting, cultural, and amusement events [1]. A unique property of such events is the high density of users. A direct result of this property is the high spatial fading correlation.

A RF front-end for digital audio broadcasting
2007 18th European Conference on Circuit Theory and Design, 2007A band 3 receiver RF front-end for digital audio broadcasting (DAB) is described in this paper. The front-end integrates most of the functions necessary to receive and down convert band 3 (174~245MHz) signals for further baseband processing, including a variable gain LNA, mixers, VGA, IF amplifiers, and PLL.

Augmenting digital audio broadcast with rich data
Proceedings of the 2005 ACM SIGCHI International Conference on Advances in computer entertainment technology, 2005HP Laboratories, GWR, Bristol University, ASL and Panasonic Semiconductor are collaborating to explore the potential of Digital Audio Broadcasting through a series of user trials. Our first iPAQ-based prototype allows listeners to GWR-Bristol to interact with a set of web pages broadcast alongside the digital audio stream and displayed on a small color

Measuring audio SNR on digital broadcast systems
IEEE Transactions on Broadcasting, 1994A spectrum analysis technique is described which will measure the quantization noise in a digital audio system with a signal present. An estimate of the power density spectrum is interpreted to find the signal to quantization noise ratio. Additional information derived from real life spectrum measurements is explained. >

DAB goes digital [digital audio broadcasting]
IEE Seminar on Broadcasting Spectrum: The Issues, 2005DAB digital radio is a remarkable technology, fulfilling its promise of reliably delivering high quality digital audio in the most challenging mobile and fixed receiver environments. DAB digital radio's success in the UK is outstripping forecasts and already it is the most listened to platform for digital radio. The same Eureka147 standard has begun to
