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.
