Applications of algebraic number theory in wireless communications

Abstract

In this talk we show how tools from algebraic number theory can be exploited to build efficient space-time codes for the use of multi-antenna wireless communications over a Rayleigh fading channel. In particular, we describe codes that are targeted to digital video broadcasting (DVB). Finally, we show how the maximum-likelihood decoding complexity of a space-time code can be reduced by imposing a certain inner structure.  

Bio

Camilla Hollanti received the M.Sc. and Ph.D. degrees from the University of Turku, Finland,
in 2003 and 2009, respectively, both in pure mathematics. Her research is in the area of applications of algebraic number theory in wireless communications and distributed storage.

Since June 2004, she has been with the Department of Mathematics, University of Turku, Finland. In 2005, she visited the Department of Algebra at Charles' University, Prague, Czech Republic for six months. During 2009-2012 she was the Principal Investigator of the Academy of Finland project "Applications of Class Field Theory in Present and Future Multiuser Communications" at the University of Turku, Finland. She joined the Department of Mathematics, University of Tampere, Finland, as a Lecturer for the academic year 2009-2010. Since November 2011, she has been with the Department of Mathematics and System Analysis at the Aalto University, Finland, as a Tenure Track Assistant Professor. 

Hollanti is a recipient of several grants from various foundations, including the Finnish Cultural Foundation research grant in 2007, the Finnish Academy of Science research grant in 2008, the Young Researcher's Project grant from the Emil Aaltonen Foundation in 2009, and the Academy of Finland project grant in 2010. 

 

The lecture will be organized with the IEEE COM/IT chapter, see http://www.cwc.oulu.fi/IEEE_COM19/
