Digital AM Radio

22.06.2004

Despite the technical advances of digital FM radio, offering increased choice and crystal clear, disturbance-free radio reception, AM (medium and long-range) radio is still the most common medium used to broadcast news and entertainment around the world. Now EUREKA project E! 2390 DIAM has combined the benefits of digital radio with the range and popularity of AM.

Following on from the work of the EUREKA project E! 1557 NADIB which defined the technical standard necessary to achieve digital audio quality for AM bands, the phase 1 of the DIAM project has developed a platform digital AM receiver, the second phase will allow to develop an affordable chip for the consumer market.

“We devised a chipset powerful enough yet small enough to minimise silicon use and energy consumption, and can now combine digital AM as well as analogue AM and FM in a single receiver,” says Dr Ben Altieri, CEO of IPiTEC Advanced DSP, an Italian subsidiary of the project’s lead partner Atmel.

Pierre Vasseur, Director of Advanced Techologies and Marketing of the French partner Thales Broadcast and Multimedia, describes how investing in the EUREKA project outside Thales’ core business area allowed it to get a return on a previous decade of investment in the digitisation of the AM bands.

“Helping to develop a chipset and a receiver opens up the market for our radio transmitter core business. If the digital radio system is successful, broadcasters will have to either upgrade their transmitters or invest in new ones. This will not only secure our existing market but should increase it by 50%.”

Vasseur regards DIAM as an incredible step forward. “We have completed long-distance trials from Europe, Canada and Australia, bringing FM quality sound and data services to regional, national and international broadcasting via the existing digitised AM channels.”

There is a massive potential market with about two billion analogue AM receivers around the world today, including India and China where long-range, low-cost and low-power radio is ideal for general communication and for distance learning in such huge countries. “We’ve already had a tremendous response and the Chinese government hopes to have digital radio in place in time for the 2008 Beijing Olympics,” says Vasseur. “As we have established a long-term relationship with Chinese receiver manufacturers we hope that they will use the DIAM chipset!”

EUREKA has enabled DIAM to be perfectly positioned for success, the partners collaborating with the major receiver manufacturers to bring the first affordable digital AM radio receivers onto the market in 2003 and early 2004.

“Without EUREKA, DIAM would not have happened,” claims Dr Altieri. “It’s much more flexible than other funding schemes and allows you to do the work you want to do without getting bogged down in bureaucracy.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
