Modeling and Mitigation of Equalization-Enhanced Phase Noise
Benedikt Geiger, Fred Buchali, Vahid Aref +1
Equalization-enhanced phase noise (EEPN) emerges as a key performance limitation in high symbol-rate coherent transmission systems. In this paper, we highlight recent advances in m…
Breaking the CP Limit: Robust Long-Range OFDM Sensing via Interference Cleaning
Umut Utku Erdem, Lucas Giroto, Benedikt Geiger +6
In orthogonal frequency-division multiplexing-based radar and integrated sensing and communication systems, the sensing range is traditionally limited by the round-trip time corres…
Constellation Shaping for OFDM-ISAC Systems: From Theoretical Bounds to Practical Implementation
Benedikt Geiger, Fan Liu, Shihang Lu +4
Integrated sensing and communications (ISAC) promises new use cases for mobile communication systems by reusing the communication signal for radar-like sensing. However, sensing an…
Neural Network-Based Single-Carrier Joint Communication and Sensing: Loss Design, Constellation Shaping and Precoding
Charlotte Muth, Benedikt Geiger, Daniel Gil Gaviria +1
We investigate the impact of higher-order modulation formats on the sensing performance of single-carrier joint communication and sensing (JCAS) systems. Several separate component…
Interference Mitigation for OFDM-based Integrated Sensing and Communications with Arbitrary Modulation Formats
Felix Artmann, Daniel Gil Gaviria, Benedikt Geiger +1
Integrated sensing and communication will be a key feature of future mobile networks, enabling highly efficient systems and numerous new applications by leveraging communication si…
A Temporal Gaussian Noise Model for Equalization-enhanced Phase Noise
Benedikt Geiger, Fred Buchali, Vahid Aref +1
Equalization-enhanced Phase Noise causes burst-like distortions in high symbol-rate transmission systems. We propose a temporal Gaussian noise model that captures these distortions…
