Power consumption and spectral efficiency analysis for uplink analog radio-over-fiber
Shehla Amir, Miguel Rodrigo Castellanos, Robert W. Heath
Radio-over-fiber centralizes radio access networks by using a low-loss optical fiber link between the remote radio head and the central unit. Analog radio-over-fiber (A-RoF) transm…
Signal Processing Foundations of Reconfigurable Antennas in the Tri-Hybrid MIMO Architecture
Nitish Vikas Deshpande, Joseph Carlson, Siyun Yang +6
To enable larger apertures in multipleinput multipleoutput MIMO systems the trihybrid MIMO architecture offers a promising lowcost and lowpower solution by introducing reconfigurab…
Beamforming with hybrid reconfigurable parasitic antenna arrays
Nitish Vikas Deshpande, Miguel Rodrigo Castellanos, Saeed R. Khosravirad +3
A parasitic reconfigurable antenna array is a low-power approach for beamforming using passive tunable elements. Prior work on reconfigurable antennas in communication theory is ba…
Embracing Reconfigurable Antennas in the Tri-hybrid MIMO Architecture for 6G and Beyond
Miguel Rodrigo Castellanos, Siyun Yang, Chan-Byoung Chae +1
Multiple-input multiple-output (MIMO) communication has led to immense enhancements in data rates and efficient spectrum management. The evolution of MIMO, though, has been accompa…
Frequency-selective beamforming and single-shot beam training with dynamic metasurface antennas
Nitish Vikas Deshpande, Joseph Carlson, Miguel R. Castellanos +1
Dynamic metasurface antennas (DMAs) beamform through low-powered components that enable reconfiguration of each radiating element. Previous research on a single-user multiple-input…
