Tutorial on Wireless Channel Charting for Massive MIMO at IEEE WCNC 2022
Prof. Studer and Dr. Guillaud will give a tutorial at the IEEE Wireless Communications and Networking Conference (WCNC) on April 10, 2022, at 14:00 CST.
Channel charting is an emerging framework that enables pseudo-positioning of user equipment (U.E.s) from channel state information (CSI) only. More concretely, channel charting associates CSI to U.E. spatial location using dimensionality reduction and manifold learning, thus enabling the infrastructure base stations or wireless access points to perform several predictive tasks relevant to emerging wireless networks that depend on U.E. location. Prominent application examples are localization relative to points-of-interest, U.E. grouping, cell handover, U.E. path prediction, predictive rate control, assisted beam-finding, etc. This tutorial aims to provide the audience with an exhaustive overview of the nascent research field of channel charting, which is at the intersection of machine learning, numerical optimization, channel modeling, and communication theory. To this end, this tutorial will (i) introduce a wide range of theoretical and algorithm-level concepts and (ii) demonstrate its efficacy with real-world results from indoor and outdoor Massive MIMO channel measurements.
