Influence of the BER on the intelligibility of the received DAB signal

For Digital Audio Broadcasting networks new planning criterions apply: The bit error rate instead of fieldstrength is used to predict the coverage areas. Since several source and channel coding mechanisms have been developed for DAB, their influence on the intelligibility of the received signal is investigated in this paper. Hence, a value for the maximum allowed bit error rate of the unprotected channel is derived. This value guarantees very good signal quality and is used as planning criterion for coverage predictions.
