ABSTRACT Digital Audio Broadcasting (DAB) is a new digital radio system that delivers radio services from the studio to the receiver. DAB is intended to deliver very high quality digital audio programmes and data services to fixed, mobile and portable receivers which can use simple whip antennas. It was developed in the 1990s by the Eureka 147 DAB project. DAB is very well suited for mobile reception and provides very high robustness against multipath reception. It allows use of single frequency networks (SFNs) for high frequency efficiency. Audio group to be evaluated with other several options from other countries. The performance offered by the methods submitted by the Eureka consortium was clearly superior so they were standardized by the MPEG as MPEG Audio Layers I, II and III. It took a long time until the final decision to which standard should be used for DAB was taken [4]. Finally, Layer II, also known as MUSICAM was chosen.
