The NETAV project aims to realize innovative digital transmitter and receiver electronics for safety-critical radio applications, particularly in aviation and shipping. Previously used purely analog components are to be replaced by modern, digitally programmable circuits in order to increase the flexibility, performance and efficiency of radio solutions. The focus is on two technical approaches: firstly, research into digitally tunable, time-discrete analog filters (N-way filters) for the highly selective suppression of interfering signal components in the receive path. Secondly, the investigation and realization of AI-supported methods for active suppression of the receiver's own transmitted signal. The N-way filters enable the reduction of classic, bulky coaxial filters, as they offer high frequency selectivity, good linearity and flexible tuning. AI-based interference suppression aims to avoid interference from neighboring transmitters or self-interference, even at high transmission powers. The aim is to significantly improve system performance in terms of interference immunity, range and signal quality compared to the state of the art. In the course of the project, requirements are jointly defined, models are simulated, demonstrators are realized and these are integrated into an overall system. The evaluation is carried out under realistic conditions in close coordination with the future users. The project thus addresses central challenges of current radio systems and creates the basis for powerful, robust and flexible electronics in safety-critical applications.

Ultra-high field magnetic resonance imaging is an advanced medical imaging technology and plays an important role in the study of brain function and neurobiology. It enables scientists to capture detailed images of the brain and track functional activity in real time. This can contribute to a better understanding of brain diseases, cognitive processes and neurological disorders. The technical goal of this project is to realize a universal integrated console for high-field MRI systems. The MRI console developed in this project surpasses all systems available commercially or as home-built systems to date and will enable OVGU and thus the state of Saxony-Anhalt to expand and secure its flagship activities in the field of MRI and neurosciences in the coming years. Furthermore, the project offers an excellent opportunity for integration into the
high-tech strategy of the state of Saxony-Anhalt with the establishment of semiconductor technology and microelectronics companies. With UIC4UHFMRI, the toolchain from design to system integration of modern semiconductor components is being established at OVGU.

In the SENSITU project, a modular and scalable monitoring system for structural health monitoring (SHM) of rotor blades on wind turbines is being investigated, analyzed, and tested in the field. The overall goal is application-oriented sensor data fusion for in-situ rotor blade monitoring using 60 GHz radar sensor technology (local SHM approach) and vibration-based rotor blade monitoring (global SHM approach). For this purpose, the Chair of Integrated Electronic Systems (IES) at the Otto-von-Guericke-University Magdeburg (OVGU) will research the miniaturized and modular sensor node which, in addition to a 60-GHz multiantenna radar system (MIMO radar), also features a precise acceleration sensor, an intelligent energy concept, an optimized sequence control as well as highly accurate wireless synchronization and efficient wireless data transmission. This enables unprecedented data quality for subsequent fusion of the spatially distributed sensors and data processing using machine learning methods.

In this phase, the needs of the authorities and organizations with security tasks (BOS) are determined. In a further step, the technical requirements are worked out from these customer requirements and compared with the technical possibilities of the Heinrich Hertz satellite (H2Sat). The overall objective of the project is to develop and subsequently test a new type of integrated data modem for the BOS, which can cover the requirements of users for integrated satellite communication not only in normal cases but also in the event of disasters and civil protection with a standardized, self-orchestrated access point. Experts from various BOS and other partners will be involved in the course of the project.
