High-Bandwidth Spatial Equalization for mmWave Massive MU-MIMO with Processing-In-Memory
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
All-digital basestation (BS) architectures enable superior spectral efficiency compared to hybrid solutions in massive multi-user MIMO systems. However, supporting large bandwidths…
Sparse Beamspace Equalization for Massive MU-MIMO mmWave Systems
Seyed Hadi Mirfarshbafan, Christoph Studer
We propose equalization-based data detection algorithms for all-digital millimeter-wave (mmWave) massive multiuser multiple-input multiple-out (MU-MIMO) systems that exploit sparsi…
Reducing the Complexity of Fingerprinting-Based Positioning using Locality-Sensitive Hashing
Larry Tang, Ramina Ghods, Christoph Studer
Localization of wireless transmitters based on channel state information (CSI) fingerprinting finds widespread use in indoor as well as outdoor scenarios. Fingerprinting localizati…
BEACHES: Beamspace Channel Estimation for Multi-Antenna mmWave Systems and Beyond
Ramina Ghods, Alexandra Gallyas-Sanhueza, Seyed Hadi Mirfarshbafan +1
Massive multi-antenna millimeter wave (mmWave) and terahertz wireless systems promise high-bandwidth communication to multiple user equipments in the same time-frequency resource.…
