Power Efficiency, Overhead, and Complexity Tradeoff in IRS-Assisted Communications -- Quadratic Phase-Shift Design
Vahid Jamali, Marzieh Najafi, Robert Schober +1
In this paper, we focus on large intelligent reflecting surfaces (IRSs) and propose a new codebook construction method to obtain a set of predesigned phase-shift configurations for…
Gridless Multidimensional Angle of Arrival Estimation for Arbitrary 3D Antenna Arrays
Matilde Sánchez-Fernández, Vahid Jamali, Jaime Llorca +1
A full multi--dimensional characterization of the angle of arrival (AoA) has immediate applications to the efficient operation of modern wireless communication systems. In this wor…
