On 14 June 2024, the Institute of Communication Systems (IKS) celebrated its 60th anniversary.

This anniversary was celebrated together with project partners, colleagues and numerous alumni in a festive colloquium and evening event. The event provided an insight into the development of digital speech and audio communication. It was also an opportunity to look back over the past six decades and to discuss future challenges and opportunities in the field of communication systems.

“We would like to thank everyone who has supported the Institute over the past 60 years and look forward to many more successful years,” the IKS announced.

Professor Jax has led the Institute since 2015. He initiated a new name and a research focus on modern digital communication systems. Research continues to focus on speech and audio communication as probably the most important and natural link between us humans. The research deals with signal processing in communication systems, e.g. in hearing aids, hearables or immersive 3D telephony. The aim is to make digital communication systems as natural as “direct” face-to-face speech communication. Both model-based digital signal processing and machine learning methods are used in innovative hybrid solutions.

One of the highlights of the event was the formal appointment of Marc Adrat as Honorary Professor. He is an internationally recognized expert in the field of Software Defined Radio, which involves programmable digital radio systems where essential transmission functions such as coding, error correction, modulation, and synchronization are implemented via software. His teaching activities focus on modern error-correcting channel coding in the course „Modern Channel Coding for Wireless Communications“, which is offered as part of the regular „Master’s programme in Electrical Engineering and Information Technology“.

“His expertise and commitment will undoubtedly continue to have a significant impact on the quality of our teaching and research,” stated the IKS.

The appointment will also strengthen the collaboration between the Faculty of Electrical Engineering and Information Technology and the Fraunhofer Institute for Communication, Information Processing and Ergonomics.

Professor Steffen Leonhardt, holder of the Chair of Medical Information Technology (MedIT) at the Helmholtz Institute for Biomedical Engineering at RWTH Aachen University, will moderate the new lecture: ‘Continuous In-Vehicle Health Monitoring Enabled with Multimodal Signal Fusion’ on 11 July 2024.

We are delighted to welcome Dr Joana M. Warnecke from the Peter L. Reichertz Institute for Medical Informatics at the Technical University of Braunschweig and the Hannover Medical School. Dr Warnecke will present her pioneering research into continuous health monitoring in vehicles. Her work focuses on the development of a redundant sensor system that enables reliable measurement of heartbeat and respiration rate. These systems use a Convolutional Neural Network (CNN) based architecture for data fusion and take into account additional sensors such as steering wheel angle and acceleration to improve signal quality.

“Our findings indicate that over half of the driving time can be utilized for in-vehicle heartbeat and respiratory rate monitoring, highlighting the efficiency and practicality of the proposed approach,”
states Warnecke.

This technology could make a significant contribution to the early detection of cardiovascular and chronic respiratory diseases by being seamlessly integrated into everyday life.

The ‘Colloquium on Biomedical Engineering and Related Areas’ is a regular series of events organised by RWTH Aachen University. The aim of the series is to provide an interdisciplinary education in these fields and to promote the interdisciplinary exchange of ideas. All students, clinicians, engineers and scientists are invited to attend this exciting lecture and exchange ideas with experts in the field of biomedical engineering.

The event will take place from 5 to 5:45 pm at the Helmholtz Institute for Biomedical Engineering at RWTH Aachen University, Pauwelsstraße 20, 52074 Aachen, Germany, seminar room 2.70.

On 17 April, Professor Antonello Monti of RWTH Aachen University will speak at the scientific meeting of the engineering and economics class of the “Nordrhein-Westfälische Akademie der Wissenschaften und der Künste” about the development goals of his discipline in terms of solving major societal challenges.

Against the background of the international situation, the energy transition process is more important than ever.The necessary technological transformation of the energy system must be approached from two angles: On the one hand, a new major player in energy supply has emerged: renewable energy. On the other hand, there are new consumers such as electromobility and heat pumps. Digitalisation is proving to be a key enabler in this process. You could even say that digitalisation is not an option, but a necessity. The power system is consequently becoming a large, programmable cyber physical infrastructure with a high level of complexity. In his presentation “The Digitalisation of the Energy Systems: from the electrons to the cloud”, Professor Monti addresses this complexity by analysing the solutions currently being developed for the different levels of the infrastructure.

” Rethinking the whole architecture means reconsider the basic principles of operation of the new power system but also the corresponding IT systems”,
announced Professor Monti, Director of the Institute for Automation of Complex Power Systems (ACS).

So what does it mean to run a digital grid? And will we be able to build a digital grid that is as reliable as the current infrastructure?

The solutions he proposes in his presentation are the result of concrete experience from large European research projects. Professor Monti leads a research group with about 50 full time scientists working intensively on the the border between energy and information and communication technologies. He is responsible for coordinating some of the most relevant European projects in this field, such as OneNet, TwinEU und int:net. His research work has received several awards, including the prestigious “IEEE Field Medal Award for Innovation in Public Infrastructure” and the “NRW Innovation Award”.

In another presentation – “Sustainable metals: contributions from basic research” – Professor Dierk Raabe from the Max Planck Institute for Sustainable Materials will address the question of whether we can succeed in decarbonising a key industry with “green steel”.
