From Antenna Abundance to Antenna Intelligence in 6G Gigantic MIMO Systems
Emil Björnson, Amna Irshad, Özlem Tugfe Demir +3
Current cellular systems achieve high spectral efficiency through Massive MIMO, which leverages an abundance of antennas to create favorable propagation conditions for multiuser sp…
Optimizing Movable Antennas in Wideband Multi-User MIMO With Hardware Impairments
Amna Irshad, Emil Björnson, Alva Kosasih +1
Movable antennas represent an emerging field in telecommunication research and a potential approach to achieving higher data rates in multiple-input multiple-output (MIMO) communic…
Enabling 6G Performance in the Upper Mid-Band by Transitioning From Massive to Gigantic MIMO
Emil Björnson, Ferdi Kara, Nikolaos Kolomvakis +3
The initial 6G networks will likely operate in the upper mid-band (7-24 GHz), which has decent propagation conditions but underwhelming new spectrum availability. In this paper, we…
Graph Neural Network Aided Expectation Propagation Detector for MU-MIMO Systems
Alva Kosasih, Vincent Onasis, Wibowo Hardjawana +4
Multiuser massive multiple-input multiple-output (MU-MIMO) systems can be used to meet high throughput requirements of 5G and beyond networks. In an uplink MUMIMO system, a base st…
NOMA Joint Decoding based on Soft-Output Ordered-Statistics Decoder for Short Block Codes
Chentao Yue, Alva Kosasih, Mahyar Shirvanimoghaddam +5
In this paper, we design the joint decoding (JD) of non-orthogonal multiple access (NOMA) systems employing short block length codes. We first proposed a low-complexity soft-output…
A Linear Bayesian Learning Receiver Scheme for Massive MIMO Systems
Alva Kosasih, Wibowo Hardjawana, Branka Vucetic +1
Much stringent reliability and processing latency requirements in ultra-reliable-low-latency-communication (URLLC) traffic make the design of linear massive multiple-input-multiple…
