Reliable Non-Line-of-Sight Intrusion Detection with Integrated Sensing and Communications Hardware
Paolo Tosi, Maximilian Bauhofer, Marcus Henninger +2
Non-line-of-sight (NLOS) sensing has the potential to enable use cases like intrusion detection in occluded areas, increasing the value provided by Integrated Sensing and Commu- ni…
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…
Precoding Design for Multi-User MIMO Joint Communications and Sensing
Charlotte Muth, Shrinivas Chimmalgi, Laurent Schmalen
We investigate precoding for multi-user (MU) multiple-input multiple-output (MIMO) joint communications and sensing (JCAS) systems, taking into account the potential interference b…
An Extension of Enumerative Sphere Shaping for Arbitrary Channel Input Distributions
Frederik Ritter, Andrej Rode, Laurent Schmalen
A non-uniform channel input distribution is key for achieving the capacity of arbitrary channels. However, message bits are generally assumed to follow a uniform distribution which…
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…
