All-Digital Massive MIMO Uplink and Downlink Rates under a Fronthaul Constraint
Y. Ettefagh, S. Jacobsson, A. Hu +2
We characterize the rate achievable in a bidirectional quasi-static link where several user equipments communicate with a massive multiple-input multiple-output base station (BS).…
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…
Beamspace Channel Estimation for Massive MIMO mmWave Systems: Algorithm and VLSI Design
Seyed Hadi Mirfarshbafan, Alexandra Gallyas-Sanhueza, Ramina Ghods +1
Millimeter-wave (mmWave) communication in combination with massive multiuser multiple-input multiple-output (MU-MIMO) enables high-bandwidth data transmission to multiple users in…
Siamese Neural Networks for Wireless Positioning and Channel Charting
Eric Lei, Oscar Castañeda, Olav Tirkkonen +2
Neural networks have been proposed recently for positioning and channel charting of user equipments (UEs) in wireless systems. Both of these approaches process channel state inform…
A 354Mb/s 0.37mm^2 151mW 32-User 256-QAM Near-MAP Soft-Input Soft-Output Massive MU-MIMO Data Detector in 28nm CMOS
Charles Jeon, Oscar Castañeda, Christoph Studer
This paper presents a novel data detector ASIC for massive multiuser multiple-input multiple-output (MU-MIMO) wireless systems. The ASIC implements a modified version of the large-…
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.…
