Joint Channel Estimation and Data Detection in Cell-Free Massive MU-MIMO Systems
Haochuan Song, Tom Goldstein, Xiaohu You +3
We propose a joint channel estimation and data detection (JED) algorithm for densely-populated cell-free massive multiuser (MU) multiple-input multiple-output (MIMO) systems, which…
Soft-Output Finite Alphabet Equalization for mmWAVE Massive MIMO
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
Next-generation wireless systems are expected to combine millimeter-wave (mmWave) and massive multi-user multiple-input multiple-output (MU-MIMO) technologies to deliver high data-…
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).…
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…
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-…
Massive MU-MIMO-OFDM Uplink with Direct RF-Sampling and 1-Bit ADCs
Sven Jacobsson, Lise Aabel, Mikael Coldrey +4
Advances in analog-to-digital converter (ADC) technology have opened up the possibility to directly digitize wideband radio frequency (RF) signals, avoiding the need for analog dow…
