  2. 11. Channel Estimation Aspects of Reconfigurable Intelligent Surfaces

    Author : Doga Gürgünoglu; Gabor Fodor; Emil Björnson; Jaap van de Beek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable intelligent surface; channel estimation; pilot contamination; positioning; angle of arrival estimation; integrated sensing and communications; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In the sixth generation of wireless communication systems (6G), there exist multiple candidate enabling technologies that help the wireless network satisfy the ever-increasing demand for speed, coverage, reliability, and mobility. Among these technologies, reconfigurable intelligent surfaces (RISs) extend the coverage of a wireless network into dead zones, increase capacity, and facilitate integrated sensing and communications tasks by consuming very low power, thus contributing to energy efficiency as well.
