Overhead-Aware Design of Reconfigurable Intelligent Surfaces in Smart Radio Environments

20 Sep 2020 Zappone Alessio Di Renzo Marco Shams Farshad Qian Xuewen Debbah Merouane

Reconfigurable intelligent surfaces have emerged as a promising technology for future wireless networks. Given that a large number of reflecting elements is typically used, and that the surface has no signal processing capabilities, a major challenge is to cope with the overhead that is required to estimate the channel state information and to report the optimized phase shifts to the surface...
