Intelligent Surface Optimization in Terahertz under Two Manifestations of Molecular Re-radiation
Anish Pradhan, J. Kartheek Devineni, Harpreet S. Dhillon +1
The operation of Terahertz (THz) communication can be significantly impacted by the interaction between the transmitted wave and the molecules in the atmosphere. In particular, it…
Pilot Assignment Schemes for Cell-Free Massive MIMO Systems
Priyabrata Parida, Harpreet S. Dhillon
In this work, we propose three pilot assignment schemes to reduce the effect of pilot contamination in cell-free massive multiple-input-multiple-output (MIMO) systems. Our first al…
Closed-form Characterization of the MGF of AoI in Energy Harvesting Status Update Systems
Mohamed A. Abd-Elmagid, Harpreet S. Dhillon
This paper considers a real-time status update system in which an energy harvesting (EH)-powered transmitter node observes some physical process, and sends its sensed measurements…
3D Two-Hop Cellular Networks with Wireless Backhauled UAVs: Modeling and Fundamentals
Morteza Banagar, Harpreet S. Dhillon
