Deep-Learning-Based Channel Estimation for Distributed MIMO with 1-bit Radio-Over-Fiber Fronthaul
Alireza Bordbar, Lise Aabel, Christian Häger +2
We consider the problem of pilot-aided, uplink channel estimation in a distributed massive multiple-input multiple-output (MIMO) architecture, in which the access points are connec…
A TDD Distributed MIMO Testbed Using a 1-Bit Radio-Over-Fiber Fronthaul Architecture
Lise Aabel, Sven Jacobsson, Mikael Coldrey +3
We present the uplink and downlink of a time-division duplex distributed multiple-input multiple-output (D-MIMO) testbed, based on a 1-bit radio-over-fiber architecture, which is l…
6G Radio Testbeds: Requirements, Trends, and Approaches
Gilles Callebaut, Liang Liu, Thomas Eriksson +3
The proof of the pudding is in the eating - that is why 6G testbeds are essential in the progress towards the next generation of wireless networks. Theoretical research towards 6G…
On the Impact of Hardware Impairments on Massive MIMO
Ulf Gustavsson, Cesar Sanchéz-Perez, Thomas Eriksson +6
Massive multi-user (MU) multiple-input multiple-output (MIMO) systems are one possible key technology for next generation wireless communication systems. Claims have been made that…
