Beamforming Tradeoffs for Initial UE Discovery in Millimeter-Wave MIMO Systems
Beamforming Tradeoffs for Initial UE Discovery in Millimeter-Wave MIMO Systems
Millimeter-wave MIMO systems have gained increasing traction towards the goal of meeting the high data-rate requirements in next-generation wireless systems. The focus of this work is on low-complexity beamforming approaches for initial UE discovery in such systems. Towards this goal, we first note the structure of the optimal beamformer with …
