On the Physical Plausibility and Distribution Alignment for Sim-to-Real RF Positioning
Ararat Saribekyan, Armen Manukyan, Hrant Khachatrian +1
Reliable radio frequency (RF) positioning from cellular measurements is limited by the high cost and limited coverage of real drive-test data, especially when models must work on s…
On the Limitations of Ray-Tracing for Learning-Based RF Tasks in Urban Environments
Armen Manukyan, Hrant Khachatrian, Edvard Ghukasyan +1
We study the realism of Sionna v1.0.2 ray-tracing for outdoor cellular links in central Rome. We use a real measurement set of 1,664 user-equipments (UEs) and six nominal base-stat…
Empirical Application Insights on Industrial Data and Service Aspects of Digital Twin Networks
Marco Becattini, Davide Borsatti, Armir Bujari +5
Digital twin networks (DTNs) serve as an emerging facilitator in the industrial networking sector, enabling the management of new classes of services, which require tailored suppor…
Outdoor Environment Reconstruction with Deep Learning on Radio Propagation Paths
Hrant Khachatrian, Rafayel Mkrtchyan, Theofanis P. Raptis
Conventional methods for outdoor environment reconstruction rely predominantly on vision-based techniques like photogrammetry and LiDAR, facing limitations such as constrained cove…
ML-based Approaches for Wireless NLOS Localization: Input Representations and Uncertainty Estimation
Rafayel Darbinyan, Hrant Khachatrian, Rafayel Mkrtchyan +1
The challenging problem of non-line-of-sight (NLOS) localization is critical for many wireless networking applications. The lack of available datasets has made NLOS localization di…
