• COFDM: The modulation system for digital radio - This paper describes the background of COFDM, the modulation system that is used for digital audio broadcasting (DAB).   
• "COFDM - The Best Asset for DAB-T" - This paper presents an educational model of the COFDM modulation, aiming to give some technical backgrounds, then it describes the characteristics the COFDM modulator shall have to allow economical implementation of large DAB_T SFN networks.
