Repeater-Aided Over-the-Air Phase Synchronization in Distributed MIMO
Unnikrishnan Kunnath Ganesan, Sai Subramanyam Thoota, Erik G. Larsson
Phase synchronization of access points (APs) in a distributed multiple-input multiple-output (D-MIMO) system is critical to leverage the performance benefits of D-MIMO. Existing ov…
Repeater Swarm-Assisted Cellular Systems: Interaction Stability and Performance Analysis
Jianan Bai, Anubhab Chowdhury, Anders Hansson +1
We consider a cellular massive MIMO system where swarms of wireless repeaters are deployed to improve coverage. These repeaters are full-duplex relays with small form factors that…
Cell-Free Massive MIMO with Multi-Antenna Users and Phase Misalignments: A Novel Partially Coherent Transmission Framework
Unnikrishnan Kunnath Ganesan, Tung Thanh Vu, Erik G. Larsson
Cell-free massive multiple-input multiple-output (MIMO) is a promising technology for next-generation communication systems. This work proposes a novel partially coherent (PC) tran…
BeamSync: Over-The-Air Synchronization for Distributed Massive MIMO Systems
Unnikrishnan Kunnath Ganesan, Rimalapudi Sarvendranath, Erik G. Larsson
In distributed massive multiple-input multiple-output (MIMO) systems, multiple geographically separated access points (APs) communicate simultaneously with a user, leveraging the b…
Joint Beamforming and Broadcasting in Massive MIMO
Erik G. Larsson, H. Vincent Poor
The downlink of a massive MIMO system is considered for the case in which the base station must concurrently serve two categories of terminals: one group to which imperfect instant…
