Title: A New Transmission Technique:  OFDM with Index Modulation

Presented by:
Professor Erdal Panayirci, Kadir Has University, Istanbul, Turkey

Abstract: In this presentation, a novel orthogonal frequency division multiplexing (OFDM) scheme, which is called OFDM with index modulation (OFDM-IM), is proposed for frequency-selective fading and fast timer-varying channels. In this scheme, inspiring from the recently introduced spatial modulation concept for multiple-input multiple-output (MIMO) channels, the information is conveyed not only by M-ary signal constellations as in classical OFDM, but also by the indices of the subcarriers, which are activated according to the incoming bit stream. Different transceiver structures are proposed and a theoretical error performance analysis is provided for the new scheme. It is shown via computer simulations that the proposed scheme achieves significantly better error performance than classical OFDM due to fact that less ICI is generated in high mobility channels and that the information bits are carried in the spatial domain by the indices of OFDM subcarriers.

Biography: Erdal Panayirci received the MS degree in Electrical Engineering from Istanbul Technical University, Istanbul, Turkey and the Ph.D. degree in Electrical Engineering and System Science from Michigan State University, East Lansing Michigan, USA.  Currently he is the Department Head of the Electrical and Electronic Engineering Department at Kadir Has University, Istanbul, Turkey.  He spent 2008-2009 academic year in Princeton University as a Visiting Research Fellow.  His research interests include communication theory, synchronization, channel estimation and equalization, multicarrier systems, coded modulation and interference cancellation with array processing and space-time coded and MIMO systems. He published extensively in the leading scientific journals and the international conferences. He has co-authored the book Principles of Integrated Maritime Surveillance Systems (Boston, Kluwer Academic Publishers, 2000).  He is the director of the Network of Excellence in Wireless Communications (NEWCOM), representing Kadir Has University, established recently by the European Commission on the Seventh Frame Program which focuses on activities in Wireless Communications research, technological development and demonstration. Prof. Panayırcı is a Fulbright-Hays Fellow, NATO Scientist Fellow and an IEEE Life Fellow. He is Member of Sigma Xi.
