01 November 2019 (13:40):  IEEE AP/MTT/EMC/ED Turkey Seminar Series (S.56)

Speaker: Prof. Sinan Gezici, Bilkent University

Topic: "Fundamental Limits and Resource Allocation for Visible Light Positioning"

Location: Middle East Technical University, Ankara, Turkey

Abstract: Visible light communication (VLC) is an emerging paradigm that facilitates multiple functionalities including illumination, high-speed data communications, and localization. Based on the VLC technology, visible light positioning (VLP) systems aim to estimate locations of VLC receivers based on light-emitting diode (LED) transmitters at known locations. VLP presents a viable alternative to radio frequency (RF)-based positioning systems by providing inexpensive and accurate localization services. In this talk, we consider the problem of localization in visible light systems and investigate distance and position estimation approaches in synchronous and asynchronous scenarios, focusing on both theoretical performance characterization and algorithm development aspects. In addition, we propose a power allocation framework for VLP systems based on convex optimization approaches. Simulation results reveal various benefits of the proposed approaches.

Bio: Sinan Gezici received the B.S. degree from Bilkent University, Turkey in 2001, and the Ph.D. degree in Electrical Engineering from Princeton University in 2006. From 2006 to 2007, he worked at Mitsubishi Electric Research Laboratories, Cambridge, MA. Since 2007, he has been with the Department of Electrical and Electronics Engineering at Bilkent University, where he is currently a Professor. Dr. Gezici's research interests are in the areas of detection and estimation theory, wireless communications, and localization systems. Among his publications in these areas is the book Ultra-wideband Positioning Systems: Theoretical Limits, Ranging Algorithms, and Protocols (Cambridge University Press, 2008). Dr. Gezici was an associate editor for IEEE Transactions on Communications, IEEE Wireless Communications Letters, and Journal of Communications and Networks.
