Learning Beamforming in Cell-Free Massive MIMO ISAC Systems
Umut Demirhan, Ahmed Alkhateeb
Beamforming design is critical for the efficient operation of integrated sensing and communication (ISAC) MIMO systems. ISAC beamforming design in cell-free massive MIMO systems, c…
Cell-Free ISAC MIMO Systems: Joint Sensing and Communication Beamforming
Umut Demirhan, Ahmed Alkhateeb
This paper considers a cell-free integrated sensing and communication (ISAC) MIMO system, where distributed MIMO access points (APs) jointly serve the communication users and sense…
Enabling Cell-Free Massive MIMO Systems with Wireless Millimeter Wave Fronthaul
Umut Demirhan, Ahmed Alkhateeb
Cell-free massive MIMO systems have promising data rate and uniform coverage gains. These systems, however, typically rely on optical fiber based fronthaul for the communication be…
Relay Aided Intelligent Reconfigurable Surfaces: Achieving the Potential Without So Many Antennas
Xiaoyan Ying, Umut Demirhan, Ahmed Alkhateeb
This paper proposes a novel relay-aided intelligent reconfigurable surface (IRS) architecture for future wireless communication systems. The proposed architecture, which consists o…
