"Space Time Codes: Theory and Heuristics"

Paul Lusina
Date: Wednesday, July 23, 2003
Time: 2:00 pm to 4:00 pm
Location: DC 1331
All Are Welcome!

Space-time codes has become an area of intense research in the area of information theory due to their promise for improved error performance and increased capacity.  These codes are composed of matrices, which are transmitted over multiple antennas and timeslots.  The inclusion of the spatial dimension has resulted in several new design criteria, which are different than those for classical channel codes.
In this presentation, the space-time design criteria from literature are presented, and the associated assumptions and terminology. A link is then made between the classical code design criteria and those for space-time codes.  It is seen that the new criteria may be seen as an extension of the classical coding theory.  Using this view, several new space-time code designs are presented and compared.
Paul Lusina received his Bachelors of Applied Science in electrical Engineering from the university of Toronto through their Engineering Science program in 1995.  He continued his studies at Queen's university in the area of beamforming, and received his Masters degree in 1997.  >From 1997 to present, he has been with the department of Telecommunications and Applied information theory at the university of Ulm in Germany.  Here, his doctorate thesis has focused on the application of algebraic coding theory to the area of space-time coding.
Mr. Lusina has worked for several companies, including a 16 month internship at Northern Telecom.  During his studies in Germany, he has been sponsored by the German Research Institute, as well as industry contracts with Siemens in the area of UMTS.
