Robust Wildfire Forecasting under Partial Observability: From Reconstruction to Prediction
Chen Yang, Mehdi Zafari, Ziheng Duan +1
Satellite-derived fire observations are the primary input for learning-based wildfire spread prediction, yet they are inherently incomplete due to cloud cover, smoke obscuration, a…
ASSENT: Learning-Based Association Optimization for Distributed Cell-Free ISAC
Mehdi Zafari, A. Lee Swindlehurst
Integrated Sensing and Communication (ISAC) is a key emerging 6G technology. Despite progress, ISAC still lacks scalable methods for joint AP clustering and user/target scheduling…
An Analytical and Experimental Study of Distributed Uplink Beamforming in the Presence of Carrier Frequency Offsets
Mehdi Zafari, Divyanshu Pandey, Rahman Doost-Mohammady
Realizing distributed multi-user beamforming (D-MUBF) in time division duplex (TDD)-based multi-user MIMO (MU-MIMO) systems faces significant challenges. One of the most fundamenta…
Coordinated Decentralized Resource Optimization for Cell-Free ISAC Systems
Mehdi Zafari, Rang Liu, A. Lee Swindlehurst
Integrated Sensing and Communication (ISAC) is emerging as a key enabler for 6G wireless networks, allowing the joint use of spectrum and infrastructure for both communication and…
Multi-Domain Optimization Framework for ISAC: From Electromagnetic Shaping to Network Cooperation
Rang Liu, Ming Li, Mehdi Zafari +2
Integrated sensing and communication (ISAC) has emerged as a key feature for sixth-generation (6G) networks, providing an opportunity to meet the dual demands of communication and…
ADMM for Downlink Beamforming in Cell-Free Massive MIMO Systems
Mehdi Zafari, Divyanshu Pandey, Rahman Doost-Mohammady +1
In cell-free massive MIMO systems with multiple distributed access points (APs) serving multiple users over the same time-frequency resources, downlink beamforming is done through…
