Paper on Beam-Slicing for Jammer Mitigation Accepted at OJCAS!
Congratulations to Gian Marti and Oscar Castañeda for the acceptance of their paper to the Special Section on Algorithms, Circuits, and Systems for Signal Processing at the Edge of the IEEE Open Journal of Circuits and Systems.
The paper "Jammer Mitigation via Beam-Slicing for Low-Resolution mmWave Massive MU-MIMO" proposes an analog spatial transform, called beam-slicing, to enable effective jammer mitigation in low- resolution mmWave massive MU-MIMO. Beam-slicing aims to prevent the jammer from driving the analog-to-digital converters (ADCs) at the base-station into saturation. To do this, beam-slicing focuses the jammers energy on only a subset of ADCs, so that the remaining ADCs are free from jamming interference. We complement beam-slicing with either of two digital equalizers that reconstruct the user signals based on the interference-free ADC outputs, resulting in the methods SNIPS and CHOPS. Our simulation results show that beam-slicing can significantly improve the effectiveness of jammer mitigation.
The paper has been co-authored by Gian Marti, Oscar Castañeda, and Prof. Christoph Studer from the IIP Group and will appear in the IEEE Open Journal of Circuits and Systems's special section on Algorithms, Circuits, and Systems for Signal Processing at the Edge.
