Performance Comparison of Joint Delay-Doppler Estimation Algorithms
Lorenz Mohr, Michael Döbereiner, Steffen Schieler +4
Integrated sensing and communications (ISAC), radar, and beamforming require real-time, high-resolution estimation algorithms to determine delay-Doppler values of specular paths wi…
Geometry-Based Drift Compensation for Distributed Channel Sounding Measurements in Dynamic Drone Scenarios
Lorenz Mohr, Marc Miranda, Sebastian Semper +5
Measured impulse responses obtained from a dynamic unmanned aerial vehicle (UAV) channel sounding system exhibit effects attributable to time-varying carrier frequency offset (CFO)…
Integrated Radio Sensing Capabilities for 6G Networks: AI/ML Perspective
Victor Shatov, Steffen Schieler, Charlotte Muth +11
The sixth-generation wireless communications (6G) is often labeled as "connected intelligence". Radio sensing, aligned with machine learning (ML) and artificial intelligence (AI),…
Measurement-based Evaluation of CNN-based Detection and Estimation for ISAC Systems
Steffen Schieler, Sebastian Semper, Christian Schneider +1
In wireless sensing applications, such as ISAC, one of the first crucial signal processing steps is the detection and estimation targets from a channel estimate. Effective algorith…
Benchmarking CFAR and CNN-based Peak Detection Algorithms in ISAC under Hardware Impairments
Paolo Tosi, Steffen Schieler, Marcus Henninger +2
Peak detection is a fundamental task in radar and has therefore been studied extensively in radar literature. However, Integrated Sensing and Communication (ISAC) systems for sixth…
Joint Delay-Doppler Estimation using OFDMA Payloads for Integrated Sensing and Communications
Marc Miranda, Sebastian Semper, Christian Schneider +2
