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…
Array Geometry-Centric Axial Sidelobe Interference Analysis for Near-Field Multi-User MIMO
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 (NF). Unlike far-field…
Spatial Degrees of Freedom in Near Field MIMO: Experimental Validation of Beamspace Perspective
Ahmed Hussain, Asmaa Abdallah, Ahmed Nasser +2
Conventional far-field multiple-input multiple-output (MIMO) channels are limited to a single spatial degree of freedom (DoF) under a line-of-sight (LoS) condition. In contrast, th…
Analyzing URA Geometry for Enhanced Near-Field Beamfocusing and Spatial Degrees of Freedom
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +2
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…
Sparse Array Design for Near-Field MU-MIMO: Reconfigurable Array Thinning Approach
Ahmed Hussain, Asmaa Abdallah, Abdulkadir Celik +2
Future wireless networks, deploying thousands of antenna elements, may operate in the radiative near-field (NF), enabling spatial multiplexing across both angle and range domains.…
