Interference Modeling for Wireless Communication Networks

Wireless communication systems are interference-limited. The structure of interference depends on chosen transmit and receive strategies. The objective of these research activities is to develop a general approach for interference modeling. The starting point of the investigation was the concept of interference functions introduced by Yates. To capture a larger class of possible transmit and receive stratgies it was necessary to introduce more general classes of interference functions. We characterized possible convex, concave and log-convex general interference functions. This characterization is the basis for cross-layer optimization.
