Treball realitzat al Institute for Theoretical Information Technology de la RWTH Aachen University[ANGLÈS] Inter-cell interference is of great interest and one of the essential issues for wireless operators who want to provide full coverage within their service area and guarantee a certain Quality of Service (QoS) to all users. In this thesis the resource allocation problem in an OFDMA based multi-cell network is formulated. Since no algorithm with polynomial running time exists due to non-linearity and combinatorial nature of underlying problem we adopted a heuristic approach with low computational cost and acceptable performance loss. We address specifically sharing available radio resources among users in terms of bandwidth allocation in...
