| Abstract | |
Interference is a limiting factor of individual and global performance in wireless communication networks. In this work, two classical interference management techniques are studied: the transmission power control and the channel equalization. Three approaches are considered for distributed and opportunistic power control. The first one is based on static non-cooperative game theory and theories of iterative functions, providing a class of algorithms. In the second approach, we propose different algorithms derived from formulations and traditional solutions of H2 control and mixed H2/Hoo control. Finally, we apply dynamic game theory to the problem for obtaining two new power control algorithms. The second part of the thesis, devoted to channel equalization, is divided into two topics. In the first one, we provide a "worst case" analysis for equalization delay by using concepts of noncooperative game theory. In the second topic, we present two proposals for the combination of the desirable characteristics of H2 and Hoo equalizers: a convex combination of the two filters and a scheme for adapting the robustness level of the Hoo filter.
