ERLANGEN, Germany — The Fraunhofer Institute for Integrated Circuits IIS say it is now offering an update to its DAB+ software library that will improve in-vehicle reception, make more stations available and add Emergency Warning Functionality.

According to Fraunhofer, the update “uses efficient spur suppression technology,” which improves digital radio reception, enabling listeners to tune in to more stations by extending the coverage range and adding to the receivable channels.

“Thanks to improved baseband processing algorithms, the solution offers dynamic resistance to interference,” said said Fraunhofer IIS Infotainment Group Manager Martin Speitel. He added, “The upgraded version of our DAB+ software library automatically suppresses any sporadic narrowband interference. Electronic vehicle components can generate interfering signals of this nature.”

Additionally, the software defined radio solution now features DAB+ Emergency Warning Functionality that includes multilingual text information about emergency situations. The company says the radios will also wake up from standby mode to share the information.
