Paper on Beam Alignment for Cell-Free mmWave Massive MU-MIMO presented at IEEE SiPS'22!
Jannik Brun presented his paper in the Cybersecurity & Telecommunication Systems Session at the 2022 IEEE Workshop on Signal Processing Systems (SiPS).
The paper "Beam Alignment for the Cell-Free mmWave Massive MU-MIMO Uplink" proposes an interference-aware method for beam alignment (BA) in the cell-free millimeter-wave (mmWave) massive multiuser (MU) multiple-input multiple-output (MIMO) uplink. In the considered scenario, the access points perform full digital receive beamforming while the user equipments perform analog transmit beamforming. The paper evaluates the method using realistic mmWave channels from a commercial ray-tracer, showing the superiority of the proposed method over omnidirectional transmission as well as over methods that do not take multi-user interference into account.
