LOCUS-DT: Localization via Observation-Conditioned Uncertainty Scoring with Digital Twins
Haozhe Lei, Roberto Bomfin, Marwa Chafii +1
Accurate indoor localization is essential for emerging applications in robotic navigation and search and rescue. While classical methods typically focus on single-point estimates,…
Near Field Multi-Band Localization: CRB, Efficient Estimator, and Threshold SNR
Roberto Bomfin, Marco Mezzavilla, Sundeep Rangan +1
This paper presents a theoretical framework for multi-band localization for a single-path single-input multiple-output (SIMO) system. We derive closed-form Cramer-Rao bounds (CRBs)…
Impact of Background Dense Multipath Components on Multi-Band Fusion ISAC Systems
Dexin Wang, Roberto Bomfin, Ahmad Bazzi +1
Multi-band sensing has emerged as a key enabler of integrated sensing and communication (ISAC), one of the six primary usage scenarios defined for IMT-2030 (6G). The introduction o…
Design of Uplink ISAC Systems with Cooperative Sensing: Power Control and Receive Beamforming
Ling He, Vaibhav Kumar, Roberto Bomfin +3
Integrated sensing and communication (ISAC) has emerged as a key paradigm for next-generation wireless systems, which allows wireless resources to be used for data transmission and…
Multi-Band Sensing in FR3 with Background Dense Multipath Components
Dexin Wang, Roberto Bomfin, Ahmad Bazzi +1
Multi-band sensing has emerged as a key enabler of integrated sensing and communication (ISAC), one of the six primary usage scenarios defined for IMT-2030 (6G). The introduction o…
Fundamental Trade-offs in Quantized Hybrid Radar Fusion: A CRB-Rate Perspective
Akhileswar Chowdary, Ahmad Bazzi, Vaibhav Kumar +2
Hybrid radar fusion (HRF), which combines monostatic and bistatic sensing in a common spectrum, offers enhanced spatial diversity, but is particularly vulnerable to quantization er…
