内容提要Outline of the Talk:

Free-Space Optical Communication With Spatial Modulation and Coherent Detection Over H-K Atmospheric Turbulence Channels

In this talk, we will be discussing the use of optical spatial modulation (OSM) as a simple low-complexity means of achieving spatial diversity in coherent free-space optical (FSO) communication systems. In particular, we will be presenting a generic analytical framework for obtaining the average bit error probability (ABEP) of un-coded and coded OSM with coherent detection in the presence of turbulence induced fading. Although the framework is general enough to accommodate any type of channel models based on turbulence scattering, the focus of the analysis is on the H-K distribution as such model is very general and valid over a wide range of atmospheric propagation conditions. Using this framework, it will shown that OSM can offer comparable performance with conventional coherent FSO schemes employing spatial diversity at the transmitter or the receiver only, while outperforming the latter in terms of spectral efficiency and hardware complexity. Furthermore, various numerical performance evaluation results are also presented and compared with equivalent results obtained by Monte Carlo simulations which verify the accuracy of the derived analytical expressions. We will be concluding this talk be briefly presenting some other research areas related to the general area of wireless telecommunications where currently we are conducting research.

P. Takis Mathiopoulos (http://gain.di.uoa.gr/index.php/the-group-members/faculty-members/p-takis-mathiopoulos , mathio@di.uoa.gr , )

P. Takis Mathiopoulos is Professor of Telecommunications at the Department of Informatics and Telecommunications, University of Athens, Greece. Prior to that, he was with the Institute for Space Applications and Remote Sensing (ISARS) of the National Observatory of Athens, first as his Director (2001 - 2005) and then as Director of Research (2006 - 2014). From 1989 - 2003, he was a faculty member in the Department of Electrical and Computer Engineering, the University of British Columbia (UBC), where he was a Professor from 2000 - 2003. From 2008 - 2013 he was appointed as Guest Professor at the Southwest Jiaotong University, China. He has been also appointed by the Government of PR of China as a Senior Foreign Expert at the School of Information Engineering, Yangzhou University (2014-2016) and by Keio University as a Visiting (Global) Professor in the Department of Information and Computer Science (2015-2016) under the Top Global University Project of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) Government of Japan.

For the last 25 years he has been conducting research mainly on the physical layer of digital communication systems for terrestrial and satellite applications, including digital communications over fading and interference environments. He co-authored a paper in GLOBECOM'89 establishing for the first time in the open technical literature the link between MLSE and multiple (or multi-symbol) differential detection for the AWGN and fading channels. He is also interested in channel characterization and measurements, modulation and coding techniques, synchronization, SIMO/MIMO, UWB, OFDM, software/cognitive radios, green communications, and 5G. In addition, since 2010, he has been actively involved with research activities in the fields of remote sensing, LiDAR systems and photogrammetry. In these areas, he has co-authored more than 100 journal papers, mainly published in various IEEE and IET journals, 4 book chapters and more than 120 conference papers. He has been PI for more than 40 research grants and has supervised the thesis of 11 PhD and 23 Master students.

Prof. Mathiopoulos has been or currently serves on the editorial board of several archival journals, including the IET Communications, and the IEEE TRANSACTIONS ON COMMUNICATIONS (1993 - 2005). He has regularly acted as a consultant for various governmental and private organizations. Since 1993, he has served on a regular basis as a scientific advisor and a technical expert for the European Commission (EC). In addition, from 2001-2014 he has served as a Greek representative to high level committees in the European Commission (EC) and the European Space Agency (ESA). He has been a member of the TPC of more than 70 international IEEE conferences, as well as TPC Vice Chair for the 2006-S IEEE VTC and 2008-F IEEE VTC as well as Co-Chair of FITCE2011. He has delivered numerous invited presentations, including plenary and key-note lectures, and has taught many short courses all over the world. As a faculty member at the ECE of UBC, he was elected ASI Fellow and a Killam Research Fellow. He was a co-recipient of two best paper awards for papers published in the 2nd International Symposium on Communication, Control, and Signal Processing (2008) and 3rd International Conference on Advances in Satellite and Space Communications (2011).
