Near Field Tapering with Slepian Window: Balancing the Range Angle Sidelobe Trade off
Ahmed Hussain, Ahmed Sultan, Asmaa Abdallah +2
Near-field beamforming enables target discrimination in both range (axial) and angle (lateral) dimensions. Elevated sidelobes along either dimension, however, increase susceptibili…
Joint Motion, Angle, and Range Estimation in Near-Field under Array Calibration Imperfections
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +1
Ultra-massive multiple-input multiple-output MIMO (UM-MIMO) leverages large antenna arrays at high frequencies, transitioning communication paradigm into the radiative near-field (…
Analyzing URA Geometry for Enhanced Spatial Multiplexing and Extended Near-Field Coverage
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +1
With the deployment of large antenna arrays at high frequency bands, future wireless communication systems are likely to operate in the radiative near-field. Unlike far-field beam…
Near-Field Beam Prediction Using Far-Field Codebooks in Ultra-Massive MIMO Systems
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +1
Ultra-massive multiple-input multiple-output (UM-MIMO) technology is a key enabler for 6G networks, offering exceptional high data rates in millimeter-wave (mmWave) and Terahertz (…
Explainable and Robust Millimeter Wave Beam Alignment for AI-Native 6G Networks
Nasir Khan, Asmaa Abdallah, Abdulkadir Celik +2
Integrated artificial intelligence (AI) and communication has been recognized as a key pillar of 6G and beyond networks. In line with AI-native 6G vision, explainability and robust…
Explainable AI-aided Feature Selection and Model Reduction for DRL-based V2X Resource Allocation
Nasir Khan, Asmaa Abdallah, Abdulkadir Celik +2
Artificial intelligence (AI) is expected to significantly enhance radio resource management (RRM) in sixth-generation (6G) networks. However, the lack of explainability in complex…
