Dasala and Knightly Win Best Paper Award at IEEE INFOCOM

The paper “Uplink Multi-User Beamforming on Single RF Chain mmWave WLANs,” authored by Keerthi Priya Dasala and Edward Knightly, in collaboration with Josep M. Jornet from Northeastern University, was awarded the best paper award at IEEE INFOCOM 2021.

In this paper, the team proposed UMBRA, a novel framework for supporting multi-stream multi-user uplink transmissions via a single RF chain. UMBRA uses novel receiver mechanisms and beam selection policies to enable multi-user uplink beamforming without additional training overhead compared to single-user systems. UMBRA is seen to achieve more than 1.45× improvement in aggregate rate compared to single-user systems.
