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…
Over-the-Air Fronthaul Signaling for Uplink Cell-Free Massive MIMO Systems
Zakir Hussain Shaik, Sai Subramanyam Thoota, Emil Björnson +1
We propose a novel resource-efficient over-the-air(OTA) computation framework to address the huge fronthaul computational and control overhead requirements in cell-free massive mul…
Resource Efficient Over-the-Air Fronthaul Signaling for Uplink Cell-Free Massive MIMO Systems
Zakir Hussain Shaik, Sai Subramanyam Thoota, Emil Björnson +1
We propose a novel resource efficient analog over-the-air (OTA) computation framework to address the demanding requirements of the uplink (UL) fronthaul between the access points (…
Data-Driven Robust Beamforming for Initial Access
Sai Subramanyam Thoota, Joao Vieira, Erik G. Larsson
We consider a robust beamforming problem where large amount of downlink (DL) channel state information (CSI) data available at a multiple antenna access point (AP) is used to impro…
