Single-Pole IIR Channel Power Prediction with Variable Delays
Jesús Arnau
Exploiting outdated channel quality indicators is crucial in most adaptive wireless communication systems. This is often done through channel prediction based on previous received…
Intersite electron correlations in a Hubbard model on inhomogeneous lattices
Nayuta Takemori, Akihisa Koga, Hartmut Hafermann
We study intersite electron correlations in the half-filled Hubbard model on square lattices with periodic and open boundary conditions by means of a real-space dual fermion approa…
Optimizing MDS Codes for Caching at the Edge
Valerio Bioglio, Frederic Gabry, Ingmar Land
In this paper we investigate the problem of optimal MDS-encoded cache placement at the wireless edge to minimize the backhaul rate in heterogeneous networks. We derive the backhaul…
Drone Small Cells in the Clouds: Design, Deployment and Performance Analysis
Mohammad Mozaffari, Walid Saad, Mehdi Bennis +1
The use of drone small cells (DSCs) which are aerial wireless base stations that can be mounted on flying devices such as unmanned aerial vehicles (UAVs), is emerging as an effecti…
Robust Pilot Decontamination Based on Joint Angle and Power Domain Discrimination
Haifan Yin, Laura Cottatellucci, David Gesbert +2
We address the problem of noise and interference corrupted channel estimation in massive MIMO systems. Interference, which originates from pilot reuse (or contamination), can in pr…
Unmanned Aerial Vehicle with Underlaid Device-to-Device Communications: Performance and Tradeoffs
Mohammad Mozaffari, Walid Saad, Mehdi Bennis +1
In this paper, the deployment of an unmanned aerial vehicle (UAV) as a flying base station used to provide on the fly wireless communications to a given geographical area is analyz…
