Electromagnetic waves are the foundation for radio communication and for many sensor applications (e.g., radar, spectroscopy) in the Internet of Things. Technical rules and standards must be defined to ensure that all processes run smoothly. These standards, some of which have been in place for decades, define how devices should communicate and work together. They ensure that everything functions properly and that devices from different manufacturers are compatible with each other. Through our research, we identify challenges for trustworthiness. We can influence standardization in a timely manner and raise awareness within the research community accordingly.
The research groups Radio Frequency Design Enablement and Wireless Connectivity and Sensing are collaborating on two topics that are particularly significant for the trustworthiness of future systems:

Self-interference (SI) is a known but critical issue at the receiver side of a monostatic radar in joint communications and sensing (JCAS) systems, and this is particularly true for high spectral-efficient waveforms. Full-duplex transceivers are usually assumed in the literature, but it is arguable if they can be taken for granted in many devices. We propose a different approach, by eliminating the SI using zero-padded (ZP) orthogonal frequency-division multiplexing (OFDM) and single-carrier frequency-division multiple access (SC-FDMA), instead of the more widespread cyclic-prefix (CP)-OFDM. ZP-sequences do not need full-duplex for the monostatic radar operation, as there is no SI between the transmit and receive antennas during the guard interval (GI), which can be used for radar detection. We derive the required radar receiver processing for ZP-sequences and CP-OFDM in time and frequency domains, respectively, to show that when the SI in JCAS is high, ZP-sequences can be beneficial, depending on the target range. Furthermore, we prove analytically that the low peak-to-average power ratio (PAPR) of ZP-SC-FDMA, when compared to ZP-OFDM, is beneficial in time-domain radar processing. This is demonstrated also by means of numerical simulation with ROC curves, for all the candidate waveforms in both coherent and incoherent receiver processing

In this paper we present the Heterogeneous Radio Mobile Simulator in Python (HermesPy), an open-source evaluator for studies on the physical layer of 6-th generation (6G) wireless systems. The software framework combines a link-level simulator, featuring a comprehensive set of models and algorithms, with hardware in the loop verification using software-defined radios. Among other features, it supports the evaluation of multi-node joint communications and sensing scenarios, which are likely to be one of the key features in 6G. We benchmark the framework's feature set against existing simulators and introduce its architectural concept. Finally, extensive simulation results demonstrating core functionalities are presented and discussed.
