Riassunto (Italiano)
This thesis is the result of a work of about six months at the Department of Computer Science Engineering of the University of Pisa.
Scope of this thesis is to study algorithms to minimize the inter-cell interference in LTE systems.
This is a "decision" problem that can be modelled as a mathematical optimization problem, more precisely as an Integer Linear Program.
We present exact and math-heuristic algorithms, whose running time depends on the number of antennas, therefore we present an extensive performance evaluation on small and large scale instances.
All the results have been obtained using the mathematical optimization tool ``IBM ILOG CPLEX Optimization Studio'' and all programs were implemented in C-C++ language.
The results are promising, indeed we show that a good coordination of antennas leads to a significant reduction of the system interference.
