Digital Radio: cooperation between Fraunhofer and STM 28-03-07

STMicroelectronics and the german Fraunhofer Institute for Integrated Circuits IIS develop a dedicated low-power Application Specific Integrated Circuit (ASIC) for Digital Radio Mondiale (DRM) applications such as fixed and portable radios, car receivers, software receivers, and Personal Digital Assistants (PDAs). Standardized by the International Electrotechnical Commission (IEC) and the European Telecommunications Standards Institute (ETSI), Digital Radio Mondiale is a universal, open standard digital radio system with FM-like sound quality available to markets worldwide for long-wave (LW), medium-wave (MW), and short-wave (SW) frequencies. In addition to providing substantially better audio quality and interference-free reception, the DRM system benefits listeners with new multimedia content such as track title, artist name and station name, which can be displayed on DRM receivers to enhance the listening experience. Unlike digital radio systems that require a new frequency allocation, DRM uses the existing Amplitude Modulation (AM) broadcast frequency bands (below 30MHz) more efficiently. The DRM signal fits into the AM broadcast-band plan and can be easily carried by many existing AM transmitters, resulting in a simple, inexpensive upgrade to the previous transmission infrastructure.
