Reconfigurable Intelligent Surfaces: A Signal Processing Perspective With Wireless Applications

2 code implementations1 Feb 2021 Emil Björnson, Henk Wymeersch, Bho Matthiesen, Petar Popovski, Luca Sanguinetti, Elisabeth de Carvalho

We will provide the formulas and derivations that are required to understand and analyze RIS-aided systems using signal processing, and exemplify how they can be utilized for improved communication, localization, and sensing.

A Globally Optimal Energy-Efficient Power Control Framework and its Efficient Implementation in Wireless Interference Networks

1 code implementation17 Dec 2018 Bho Matthiesen, Alessio Zappone, Karl-L. Besser, Eduard A. Jorswieck, Merouane Debbah

Specifically, thanks to its reduced complexity, the proposed method can be used to train an artificial neural network to predict the optimal resource allocation.
