Reconfigurable Intelligent Surfaces: Bridging the gap between scattering and reflection
J. Bucheli Garcia, A. Sibille, M. Kamoun
In this work we address the distance dependence of reconfigurable intelligent surfaces (RIS). As differentiating factor to other works in the literature, we focus on the array near…
Experimental realization of Fermi-Pasta-Ulam-Tsingou recurrence in a long-haul optical fiber transmission system
Jan-Willem Goossens, Hartmut Hafermann, Yves Jaouën
The integrable nonlinear Schrödinger equation (NLSE) is a fundamental model of nonlinear science which also has important consequences in engineering. The powerful framework of the…
Data Transmission based on Exact Inverse Periodic Nonlinear Fourier Transform, Part II: Waveform Design and Experiment
Jan-Willem Goossens, Hartmut Hafermann, Yves Jaouën
The nonlinear Fourier transform has the potential to overcome limits on performance and achievable data rates which arise in modern optical fiber communication systems when nonline…
Data Transmission based on Exact Inverse Periodic Nonlinear Fourier Transform, Part I: Theory
Jan-Willem Goossens, Hartmut Hafermann, Yves Jaouën
The nonlinear Fourier transform (NFT) decomposes waveforms propagating through optical fiber into nonlinear degrees of freedom, which are preserved during transmission. By encoding…
Practical Product Code Construction of Polar Codes
Carlo Condo, Valerio Bioglio, Hartmut Hafermann +1
In this paper, we study the connection between polar codes and product codes. Our analysis shows that the product of two polar codes is again a polar code, and we provide guideline…
The Quijote simulations
Francisco Villaescusa-Navarro, ChangHoon Hahn, Elena Massara +26
The Quijote simulations are a set of 44,100 full N-body simulations spanning more than 7,000 cosmological models in the hyperplane.…
