Efficient Computation of Physics-Compliant Channel Realizations for (Rich-Scattering) RIS-Parametrized Radio Environments
Hugo Prod'homme, Philipp del Hougne
Physics-compliant channel models of RIS-parametrized radio environments require the inversion of an "interaction matrix" to capture the mutual coupling between wireless entities (t…
On the Tacit Linearity Assumption in Common Cascaded Models of RIS-Parametrized Wireless Channels
Antonin Rabault, Luc Le Magoarou, Jérôme Sol +4
We analytically derive from first physical principles the functional dependence of wireless channels on the RIS configuration for generic (i.e., potentially complex-scattering) RIS…
Self-Adaptive RISs Beyond Free Space: Convergence of Localization, Sensing and Communication under Rich-Scattering Conditions
Chloé Saigre-Tardif, Philipp del Hougne
We discuss the need for a confluence of localization, sensing and communications if RISs are to be deployed in a self-adaptive manner in the dynamically evolving rich-scattering se…
A self-adaptive RIS that estimates and shapes fading rich-scattering wireless channels
Chloé Saigre-Tardif, Philipp del Hougne
We present a framework for operating a self-adaptive RIS inside a fading rich-scattering wireless environment. We model the rich-scattering wireless channel as being double-paramet…
PhysFad: Physics-Based End-to-End Channel Modeling of RIS-Parametrized Environments with Adjustable Fading
Rashid Faqiri, Chloé Saigre-Tardif, George C. Alexandropoulos +3
Programmable radio environments parametrized by reconfigurable intelligent surfaces (RISs) are emerging as a new wireless communications paradigm, but currently used channel models…
