DQN-based Beamforming for Uplink mmWave Cellular-Connected UAVs
Susarla Praneeth, Gouda Bikshapathi, Deng Yansha +3
Unmanned aerial vehicles (UAVs) are the emerging vital components of millimeter wave (mmWave) wireless systems. Accurate beam alignment is essential for efficient beam-based mmWave…
Joint Minimum DL-UL Rate Maximization for Cell-Free Massive MIMO
Bikshapathi Gouda, Italo Atzeni, Antti Tölli
In cell-free massive multiple-input multiple-output (MIMO) systems, the beamforming strategies at the base stations (BSs) and user equipments (UEs) can be computed building on bi-d…
Low-complexity Multicast Beamforming for Multi-stream Multi-group Communications
Hamidreza Bakhshzad Mahmoodi, Bikshapathi Gouda, MohammadJavad Salehi +1
In this paper, assuming multi-antenna transmitter and receivers, we consider multicast beamformer design for the weighted max-min-fairness (WMMF) problem in a multi-stream multi-gr…
Distributed Precoding Design via Over-the-Air Signaling for Cell-Free Massive MIMO
Italo Atzeni, Bikshapathi Gouda, Antti Tölli
Most works on cell-free massive multiple-input multiple-output (MIMO) consider non-cooperative precoding strategies at the base stations (BSs) to avoid extensive channel state info…
