Masked Latent Prediction of CSI for Indoor Localization in Integrated Sensing and Communication Systems
Ibtissam Labriji, Mahdi Maleki, Pavan Koteshwar Srinath
Channel State Information (CSI)-based fingerprinting can enable accurate indoor localization but suffers from domain shift, limited labeled data, and degraded performance in multip…
Towards Channel Charting Enhancement with Non-Reconfigurable Intelligent Surfaces
Mahdi Maleki, Reza Agahzadeh Ayoubi, Marouan Mizmizi +1
We investigate how fully-passive electromagnetic skins (EMSs) can be engineered to enhance channel charting (CC) in dense urban environments. We employ two complementary state-of-t…
Chartwin: a Case Study on Channel Charting-aided Localization in Dynamic Digital Network Twins
Lorenzo Cazzella, Francesco Linsalata, Mahdi Maleki +3
Wireless communication systems can significantly benefit from the availability of spatially consistent representations of the wireless channel to efficiently perform a wide range o…
Channel Charting in Smart Radio Environments
Mahdi Maleki, Reza Agahzadeh Ayoubi, Marouan Mizmizi +1
This paper introduces the use of static electromagnetic skins (EMSs) to enable robust device localization via channel charting (CC) in realistic urban environments. We develop a ri…
