Interference Coordination in Cellular OFDMA Networks.

The article presents a study which examines the interference coordination (IFCO) in cellular orthogonal frequency division multiple access (OFDMA) networks. It accounts on the uses of the OFDMA and the possible mitigation of IFCO through code division multiple access. It provides an overview of the IEEE 802.16e standard or the WiMAX networks which uses OFDM transmission technique and the classification of the IFCO schemes. The area-dependent and area-independent metrics were discussed to evaluate the performance of the interference coordination algorithms. It delineates the use of IFCO in the global system knowledge of ad hoc networks and cellular OFDMA networks. It discusses the possibilities of applying IFCO in the local system knowledge.
