Revisiting Matching Pursuit: Beyond Approximate Submodularity
Ehsan Tohidi, Mario Coutino, David Gesbert
We study the problem of selecting a subset of vectors from a large set, to obtain the best signal representation over a family of functions. Although greedy methods have been widel…
D-Band RIS as a Reflect Array: Characterization and Hardware Impairments Study
Ehsan Tohidi, Robert Stoecker, Julia-Marie Koeszegi +1
Reflecting intelligent surface (RIS) has emerged as a promising technology for enhancing wireless communication performance and enabling new applications in 6G networks with potent…
Near-Optimal LOS and Orientation Aware Intelligent Reflecting Surface Placement
Ehsan Tohidi, Sven Haesloop, Lars Thiele +1
Due to their passive nature and thus low energy consumption, intelligent reflecting surfaces (IRSs) have shown promise as means of extending coverage as a proxy for connection reli…
