RDS - Radio Data System a Challenge and a Solution
RDS - Radio Data System A Challenge and a Solution Michael Daucher Eduard Gärtner Michael Görtler Werner Keller Hans Kuhr Abstract The launch of the FM broadcasting system in the middle of the 20th century constituted an enormous improve- ment compared to AM. Nevertheless it turned out that car radios cannot reach the performance level of stationary receivers. Therefore in Europe the RDS system has been developed. It provides among other features for increased convenience also specific functions to overcome the performance problems of car radios to a large extent. RDS is the most complex technology to receive analog broadcasting stations. To use this technology to the full extent it requires a lot of know how about the specific reception problems in the field, RDS and reception technol- ogy in general. All this leads to a large and very complex software solution. This paper describes the main reception problems of car radios. The basic features of RDS are explained short- ly. The main part of this essay deals with the software and the required tools. It is shown, based on three key issues, how these problems can be solved with high sophisticated software. The tool for monitoring the behaviour in the field, dedicated for detailed analysis and evaluation, is explained in detail. At the end the results of different test drives show the evidence that this new RDS software developed by Technical Center Nuremberg has reached a performance which is state of the art. 41 FUJITSU TEN TECHNICHAL JOURNAL 1 RDS1 RDS - Introduction. - Introduction.

Podcasting was booming, but the gear to do it with was sputtering. Podcasters had to choose between equipment that was overly engineered and expensive, or so inexpensive and simple that quality was sacri ced. But Bryan had a solution: a broadcast-quality dynamic microphone with a built-in USB interface. It had to sound great right out of the box, with ease of use for both novice and pro. -
Analysis of the Single Frequency Network Gain in Digital Audio Broadcasting Networks †
sensors Article Analysis of the Single Frequency Network Gain in Digital Audio Broadcasting Networks † Kamil Staniec Telecommunications and Teleinformatics Department, Wrocław University of Science and Technology, 50-370 Wrocław, Poland; [email protected] † This paper is an extended version of the published conference paper “Staniec, K. SFN gain analysis in digital audio broadcasting networks. In Proceedings of the Microwave and Radar Week (MRW’20), MIKON 2020, Warsaw, Poland, 5–7 October 2020”. Abstract: The single frequency network (SFN) is a popular solution in modern digital audio and television system networks for extending effective coverage, compared to its traditional single- transmitter counterpart. As benefits of this configuration appear to be obvious, this paper focuses on the exact analysis of so-called SFN gain—a quantitative effect of advantage in terms of the received signal strength. The investigations cover a statistical analysis of SFN gain values, obtained by means of computer simulations, with respect to the factors influencing the coverage, i.e., the protection level, the reception mode (fixed, portable, mobile), and the receiver location (outdoor, indoor). The analyses conclude with an observation that the most noteworthy contribution of the SFN gain is observed on the far edges of the networks, and the least one close to the transmitters. It is also observed that the highest values of the SFN gain can be expected in the fixed mode, while the protection level has the lowest impact.
