Abstract
Radio broadcasting technology has evolved rapidly over the last few years due to ever increasing demands for as high quality sound services with ancillary data transmission in mobile environment. The Eureka-147 Digital Audio Broadcasting (DAB) system with coded OFDM technology accomplish this demand by making receivers highly robust against effects of multipath fading environment. In this paper, we have analyzed the performance of DAB system conforming to the parameters established by the ETSI (EN 300 401) using frequency interleaving and different coding rates in different transmission channels. The results show that interleaving is essential for the forward error correction to work properly and an increased coding rate makes the system more flexible without increase in the receiver complexity.
