DRM Digital Radio Mondiale: International Acceptance through Field Test Platform in Hanover

Ampegon supports one of the worldwide leading DRM test locations with a solid state low power transmission system to enable verified measurements, tests and reports

Turgi, Switzerland, March20, 2015. Ampegon has granted a solid state low power (500 W) transmission solution to RFmondial GmbH in Hannover, Germany. In cooperation with the Institute of Communication Technology (IKT) at the Leibniz Universität Hannoverthe transmitter enables technologists to continue expert measurements and demonstrations of the DRM standard on regular city environmental broadcasting conditions. A broadcast license for 26.045 MHz shortwave has been given to the Leibniz Universität Hannover.

The installation will bring DRM technology and research equipment to the campus laboratory allowing technical demonstrations for professional listeners and reception results. The use of the equipment in mobile configuration enables a testing environment for improved car radio receivers with live reception inside a city. The unlimited access and the flexible operation of the broadcast chain including all possible configurations and power levels will help to test and demonstrate DRM live broadcast and will show the technical strength of the technology. The equipment is fully remote accessible for unmanned operation.

New algorithms, coding and power improvements will be tested and verified. System linearization and coverage conditions for several operation modes are under examination. The measurements and reports are well received in international technical publications and conferences.

This DRM installation is a complete DRM service chain maintained and operated by RFmondial together with the Leibniz Universität Hannoverandthe support of Fraunhofer IIS. It co-exists next to a DRM transmission in the FM band at 95.2 MHz. In parallel to experiments under their own supervision, the service is offered to receiver, module or chip-set manufacturers to verify and improve their implementations under real environmental conditions.

About Leibniz Universität Hannover

The scope of the department of Communication Systems at the Institute of Communications Technology of the Leibniz Universität Hannover covers industrial, public & safety and multimedia communications as well as acoustics, audio and biomedical signal processing in combination with development of algorithms for medical technology and telemetry applications. The core area is in transmission and signal processing techniques for todays and future radio systems and medical technology. One part is the development and evaluation spectrally efficient modulation techniques for5th generation cellular mobile radio (5G), for local radio systems providing high data rates as well as for special applications with strict latency and resilience requirements. Current topics are the investigations on new transmission techniques for 5G, statistical signal analysis as well as synchronization and adaption aspects of multicarrier schemes (FBMC / OQAM-OFDM) with excellent coexistence capabilities for application in MTC and multi-service scenarios. The scientific work within the institute is analytic and measurement based, where for the latter one testbeds, demonstrators and prototype systems are used, and is usually done in cooperation with scientific and industrial partners (radio equipment providers, wireless entertainment equipment).
