AI for mobile communications and faster data transmission - these are the two current technological challenges faced by this year's winners of the VDE Bayern Awards. Among them are Florian Strasser, doctoral student at the Chair of Signal Processing and Johannes Zerwas, former doctoral student at the Chair of Communication Networks.
For the 16th time now, the Bavarian regional association of the VDE is honoring outstanding work and innovations from the world of science, among others, with its awards. Innovative approaches are to be presented to a wider public. At the same time, the award is intended to encourage students and young scientists to become active in research and development themselves. The VDE is a technical-scientific association with the core topics of testing, certification and application consulting in the field of electrical engineering. Using artificial intelligence for greater efficiency and quality in mobile communications and WLAN.
Using artificial intelligence for greater efficiency and quality in mobile communications and WLAN
The performance of everyday technologies such as mobile communications and Wi-Fi depends to a large extent on precise channel models that make wireless connections stable and efficient. This is the only way to meet the increasing demands placed on wireless communication.
To contribute to this, Florian Strasser used the method of diffusion models for communications engineering in his master's thesis. These are generative AI models that were previously used primarily in image processing. Thanks to Strasser's further development, they can be adapted to the specific requirements of wireless communication. This made it possible to create a channel estimator that works faster and more efficiently and is independent of the signal quality - a previously unsolved problem.
Making networks more powerful with optical technologies
The internet is growing and making ever more complex demands, meaning that network operators are increasingly reaching their limits. For example, the smooth flow of data for video streaming or cloud services at peak loads is already a challenge today.
In his doctoral thesis, Dr. Johannes Zerwas investigated the question of whether networks can be made more efficient through the use of reconfigurable optical technologies. As a result, he developed “Duo”, a novel architecture for data centers that guarantees high performance in data transmission and can still be implemented with commercially available devices.
