Unsupervised Statistical Feature-Guided Diffusion Model for Sensor-based Human Activity Recognition

no code implementations30 May 2023 Si Zuo, Vitor Fortes Rey, Sungho Suh, Stephan Sigg, Paul Lukowicz

The proposed method aims to generate synthetic time-series sensor data without relying on labeled data, addressing the scarcity and annotation difficulties associated with real-world sensor data.

Generative Adversarial Network Human Activity Recognition +1

User Localization using RF Sensing: A Performance comparison between LIS and mmWave Radars

no code implementations17 May 2022 Cristian J. Vaca-Rubio, Dariush Salami, Petar Popovski, Elisabeth de Carvalho, Zheng-Hua Tan, Stephan Sigg

Since electromagnetic signals are omnipresent, Radio Frequency (RF)-sensing has the potential to become a universal sensing mechanism with applications in localization, smart-home, retail, gesture recognition, intrusion detection, etc.

Energy-Efficient Design for RIS-assisted UAVcommunications in beyond-5G Networks

no code implementations24 Sep 2021 Anay Ajit Deshpande, Cristian J. Vaca-Rubio, Salman Mohebi, Dariush Salami, Elisabeth de Carvalho, Petar Popovski, Stephan Sigg, Michele Zorzi, Andrea Zanella

The usage of Reconfigurable Intelligent Surfaces (RIS) in conjunction with Unmanned Ariel Vehicles (UAVs) is being investigated as a way to provide energy-efficient communication to ground users in dense urban areas.

Integrating Sensing and Communication in Cellular Networks via NR Sidelink

no code implementations15 Sep 2021 Dariush Salami, Ramin Hasibi, Stefano Savazzi, Tom Michoel, Stephan Sigg

Since electromagnetic signals, through cellular communication systems, are omnipresent, RF sensing has the potential to become a universal sensing mechanism with applications in smart home, retail, localization, gesture recognition, intrusion detection, etc.
