A 39pJ/b 7.3Gbps 1.3mm Multi-Subcarrier Massive MU-MIMO-OFDM Detector Exploiting Beamspace Sparsity and Frequency-Domain Correlation in 22FDX
Abhishek Kumar, Seyed Hadi Mirfarshbafan, Oscar Castañeda +1
We present the first multi-subcarrier massive multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) data detector reported in the…
Mitigating SAR-ADC Non-Idealities in Massive MU-MIMO Systems via Affine Models
Jérémy Guichemerre, Christoph Studer
Low-resolution data converters can significantly reduce the power consumption and silicon area of all-digital massive multi-user (MU) multiple-input multiple-output (MIMO) basestat…
Neural Integrated Sensing and Communication for the MIMO-OFDM Downlink
Ziyi Wang, Frederik Zumegen, Christoph Studer
The ongoing convergence of spectrum and hardware requirements for wireless sensing and communication applications has fueled the integrated sensing and communication (ISAC) paradig…
A Deep-Unfolding-Optimized Coordinate-Descent Data-Detector ASIC for mmWave Massive MIMO
Zixiao Li, Seyed Hadi Mirfarshbafan, Oscar Castañeda +1
We present a 22 nm FD-SOI (fully depleted silicon-on-insulator) application-specific integrated circuit (ASIC) implementation of a novel soft-output Gram-domain block coordinate de…
A Software-Defined and Distributed Wi-Fi Channel-State Information Acquisition Testbed
Frederik Zumegen, Christoph Studer
We propose a software-defined testbed for Wi-Fi channel-state information (CSI) acquisition. This testbed features distributed software-defined radios (SDRs) and a custom IEEE 802.…
Efficient and Physically-Consistent Modeling of Reconfigurable Electromagnetic Structures
Alexander Stutz-Tirri, Georg Schwan, Christoph Studer
Reconfigurable electromagnetic structures (REMSs), such as reconfigurable reflectarrays (RRAs) or reconfigurable intelligent surfaces (RISs), hold significant potential to improve…
A 46 Gbps 12 pJ/b Sparsity-Adaptive Beamspace Equalizer for mmWave Massive MIMO in 22FDX
Seyed Hadi Mirfarshbafan, Christoph Studer
We present a GlobalFoundries 22FDX FD-SOI application-specific integrated circuit (ASIC) of a beamspace equalizer for millimeter-wave (mmWave) massive multiple-input multiple-outpu…
Channel Charting for Streaming CSI Data
Sueda Taner, Maxime Guillaud, Olav Tirkkonen +1
Channel charting (CC) applies dimensionality reduction to channel state information (CSI) data at the infrastructure basestation side with the goal of extracting pseudo-position in…
