Insights on the Uplink Operation of a 1-bit Radio-Over-Fiber Architecture in Multi-User D-MIMO Communication
Lise Aabel, Giuseppe Durisi, Frida Olofsson +3
We consider a distributed multiple-input multiple-output (D-MIMO) testbed in which, to enable coherent-phase transmission without over-the-air synchronization, the remote radio hea…
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…
EVM Analysis of Distributed Massive MIMO with 1-Bit Radio-Over-Fiber Fronthaul
Anzhong Hu, Lise Aabel, Giuseppe Durisi +4
We analyze the uplink performance of a distributed massive multiple-input multiple-output (MIMO) architecture in which the remotely located access points (APs) are connected to a c…
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…
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…
