Robust Near-Field Beamforming for Millimeter Wave Communication System with Aperture Perturbations

Gerald C. Nwalozie, Damir Rakhimov, Martin Haardt

ICASSP 2024accepted

In this paper, we develop a near-field beamforming algorithm that is robust against aperture deformations. We derive analytical expressions on the bounds of the elements of the steering vector as a function of the known bounds of the coordinate displacement. We apply these bounds during the optimiza…

Equivalence of Aperture Reduction in Element Space and Constrained Combination of DFT Beams in Beamspace

Damir Rakhimov, Martin Haardt

ICASSP 2023accepted

In this paper, we present an analytical proof of equivalence of the signal processing in the reduced aperture element space and in beamspace produced by the combination of multiple adjacent DFT beams with a subsequent constraining of the resulting magnitudes. This link finds applications in millimet…
