چکیده
The new digital radio system DAB (Digital Audio Broadcasting), developed within the Eureka 147 project is a very innovative and universal multimedia broadcast system that has the potential to replace existing AM and FM audio broadcast services in many parts of the world in the near future. DAB employs coded OFDM technology that enables it for mobile reception and makes receivers highly robust against channel multipath fading effect. In this paper, we have analyzed the bit error rate (BER) performance of DAB system conforming to the parameters established by the ETSI (EN 300 401) using frequency interleaving and Forward Error Correction (FEC) in different transmission channels. The results shows DAB to be suitable radio broadcasting technology for high performance in mobile environment. KeywordsDAB, OFDM, Multipath effect, frequency interleaving, FEC.

The Eureka-147 system is based on a programme multiplex which carries a combination of many separate services, each at a variety of bit-rates. However, given the international flavour of satellite broadcasting, it is likely that these services would originate from widely separated locations and this creates the problem of how the various data streams can be brought together into a single DAB mu...
