Tutorial: Factor Graphs in Wireless Communication

[26 Jan. 2012] In his tutorial “Factor Graphs in Wireless Communication: Theory and Practice”, Dr. Henk Wymeersch of the Technical University of Chalmers, Sweden, discussed the theory of Bayesian graphical models and presented several practical applications.
   
The theoretical part of the tutorial focused on the three fundamental problems of Bayesian interference and the difficulties due to the high computational complexity in their application to problems with many dimensions. Wymeersch introduced factor graphs to depict high-dimensional distributions. Factor graphs enable execution of many message passing algorithms that Wymeersch links to the fundamental problems of Bayesian interference. In the practical part of the tutorial he applied factor graphs as a solution method for three problems: receiver design, synchronization and cooperative signal processing in networks.

Wymeersch is assistant professor at the Department for Signals and Systems of the Technical University of Chalmers. He cooperates with FORCE, a research center for optical communication, and is coordinator of COOPNET, an ERC project for cooperative networks.
Wymeersch held the tutorial at ACCM on invitation of Univ.Prof. Dr. Andreas Springer, coordinator of the Area Wireless Technologies at ACCM and head of the Institute for Telecommunications and High-Frequency Systems at JKU.
