Tutorial : XL MIMO with Programmable Metasurfaces: Integration of Communications, Sensing, and Computing
Room: TBA
Tutorial Speaker: George C. Alexandropoulos, National and Kapodistrian University of Athens (NKUA), Greece & University of Illinois Chicago, USA
Abstract
The tutorial will cover the latest advances in eXtremely Large (XL) Multiple-Input Multiple-Output (MIMO) wireless systems as well as their emerging applications, giving emphasis on a generic multi-hybrid transceiver hardware architecture comprising programmable metasurfaces, which offers signal processing capabilities both in the digital and analog domains as well as over-the-air (a.k.a. wave domain) via the direct manipulation of the electromagnetic waves. System models and signal processing schemes enabling energy- and cost-efficient multi-user wireless communications, localization, and sensing, as well as their integrated realization will be discussed. In addition, emerging centralized and distributed XL MIMO systems leveraging nonlinear signal processing components and performing over-the-air inference tasks will be presented. The seminar will be concluded with a list of novel perspectives and future directions for metasurface-based XL MIMO computing in future wireless networks.
