A Novel Phenomenological Model of Equalization-enhanced Phase Noise
Benedikt Geiger, Fred Buchali, Vahid Aref +1
We show that equalization-enhanced phase noise manifests as a time-varying, frequency-dependent phase error, which can be modeled and reversed by a time-varying all-pass finite imp…
Integrated Long-range Sensing and Communications in Multi Target Scenarios using CP-OFDM
Benedikt Geiger, Silvio Mandelli, Marcus Henninger +3
6G communication systems promise to deliver sensing capabilities by utilizing the orthogonal frequency division multiplexing (OFDM) communication signal for sensing. However, the c…
Joint Optimization of Geometric and Probabilistic Constellation Shaping for OFDM-ISAC Systems
Benedikt Geiger, Fan Liu, Shihang Lu +2
6G communications systems are expected to integrate radar-like sensing capabilities enabling novel use cases. However, integrated sensing and communications (ISAC) introduces a tra…
Bistatic OFDM-based ISAC with Over-the-Air Synchronization: System Concept and Performance Analysis
David Brunner, Lucas Giroto de Oliveira, Charlotte Muth +8
Integrated sensing and communication (ISAC) has been defined as one goal for 6G mobile communication systems. In this context, this article introduces a bistatic ISAC system based…
