RF Chain Count to Mitigate Beam Split in Wideband Hybrid Arrays: From Far-Field to Near-Field
Ahmed Hussain, Asmaa Abdallah, Asmaa Abdallah Senior Member +4
Deploying large antenna arrays transitions wireless communication into the radiative near-field (NF), where spherical wavefronts enable beamfocusing in the joint angle-distance dom…
WALoMA: A Multitask Wireless Foundation Model via Adaptive Low-Rank Masked Autoencoders
Madi Makin, Asmaa Abdallah, Abdulkadir Celik +1
This paper proposes a multitask wireless foundation model via adaptive low-rank masked autoencoders (WALoMA), a unified multi-task foundation model for sixth-generation (6G) wirele…
Enwar 3.0: An Agentic Multi-Modal LLM Orchestrator for Situation-Aware Beamforming, Blockage Prediction, and Handover Management
Ahmad M. Nazar, Abdulkadir Celik, Asmaa Abdallah +3
Maintaining robust millimeter-wave (mmWave) connectivity in vehicular networks requires real-time adaptation to environmental dynamics, sensor degradation, and link variability. Th…
Boosting Spectral Efficiency via Spatial Path Index Modulation in RIS-Aided mMIMO
Ahmet M. Elbir, Abdulkadir Celik, Asmaa Abdallah +1
Next generation wireless networks focus on improving spectral efficiency (SE) while reducing power consumption and hardware cost. Reconfigurable intelligent surfaces (RISs) offer a…
Array Geometry-Centric Axial Sidelobe Interference Analysis for Near-Field Multi-User MIMO
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +1
