  5. 4. DAB Transmission System Simulation

    University essay from Institutionen för systemteknik

    Author : Héctor Uhalte Bilbao; [2004]
    Keywords : Electronics; DAB; Terrestrial digital broadcasting; OFDM; COFDM; IFFT; FFT; SFN; SimulinkTM< sup>; Differential modulator.; Elektronik;

    Abstract : DAB (Digital Audio Broadcasting) is the radio digital system developed as an european standard by the ETSI, EN 300 400, based on the Eureka-147 group works, to improve the performance of the analogue radio systems (AM and FM). The system is based on the OFDM technology which allows DAB to exploit the spectrum frequencies in a better way with a higher quality of sound for mobile receivers specially. READ MORE
