Simulation of Digital Audio Broadcasting System in QPSK, AWGN and RICIAN Channel
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. Digital Audio Broadcasting (DAB) system developed within the Eureka 147 Project is a new digital radio technology for broadcasting radio stations that provides high-quality audio and data services to both fixed and mobile receivers. The system uses COFDM technology that combats the effect of multipath fading & ISI and makes it spectrally more efficient compared with existing AM/FM systems. This paper presents the performance analysis of Eureka-147 DAB system. DAB transmission mode-II is implemented first and then extended successfully to other modes.
