Abstract: Inexpensive and rapid computational power provided powerful tools to overcome the limitations of current technologies and enabled us to apply several advanced statistical signal processing techniques for the design of receivers in wireless communications systems. In this presentation, we first mention the knowledge gaps in general. Then, we briefly explain two techniques, namely, (i) the expectation maximization (EM) and its modified version called the space-alternating generalized expectation maximization (SAGE) algorithm (ii) the Monte Carlo Markov Chain (MMCC) technique based on the Gibbs Sampling algorithm.

To demonstrate the applications of these techniques to wireless communications, we will then give two examples from our recent research, carried out with Princeton University jointly. The first one is on CDMA, entitled "computationally efficient, joint transmission delay and channel parameter estimation algorithm for uplink asynchronous direct-sequence CDMA systems", and the second one is entitled   "OFDM receiver design in the presence of high mobility fading channels". The presentation will end with a conclusion.

Biography: Erdal Panayirci received the MS degree in Electrical Engineering from Istanbul Technical University, Istanbul, Turkey in 1964 and the Ph.D. degree in Electrical Engineering and System Science from Michigan State University, East Lansing Michigan, USA, in 1970. He spent 2008-2009 academic year in Princeton University as a Visiting Research Fellow. Currently he is the Department Head  of the Electronic Engineering  Department at Kadir Has University, Istanbul, Turkey.   His research interests include communication theory, synchronization 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 Sixth Frame Program which focuses on activities in the field of research, technological development and demonstration. Prof. Panayirci is a Fulbright-Hays Fellow, NATO Scientist Fellow and IEEE Fellow. He is Member of Sigma Xi.
