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…
Multi-Tier Computing-Enabled Digital Twin in 6G Networks
Kunlun Wang, Yongyi Tang, Trung Q. Duong +3
Digital twin (DT) is the recurrent and common feature in discussions about future technologies, bringing together advanced communication, computation, and artificial intelligence,…
On the IRS Deployment in Smart Factories Considering Blockage Effects: Collocated or Distributed?
Yixin Zhang, Saeed R. Khosravirad, Xiaoli Chu +1
In this article, we study the collocated and distributed deployment of intelligent reflecting surfaces (IRS) for a fixed total number of IRS elements to support enhanced mobile bro…
A generalization of the achievable rate of a MISO system using Bode-Fano wideband matching theory
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
Impedance-matching networks affect power transfer from the radio frequency (RF) chains to the antennas. Their design impacts the signal to noise ratio (SNR) and the achievable rate…
Structure-Enhanced DRL for Optimal Transmission Scheduling
Jiazheng Chen, Wanchun Liu, Daniel E. Quevedo +3
Remote state estimation of large-scale distributed dynamic processes plays an important role in Industry 4.0 applications. In this paper, we focus on the transmission scheduling pr…
A wideband generalization of the near-field region for extremely large phased-arrays
Nitish Deshpande, Miguel R. Castellanos, Saeed R. Khosravirad +3
The narrowband and far-field assumption in conventional wireless system design leads to a mismatch with the optimal beamforming required for wideband and near-field systems. This d…
Jamming Resilient Indoor Factory Deployments: Design and Performance Evaluation
