A novel Inter-Cell Interference Coordination scheme for OFDMA system

In this paper, a novel Inter-Cell Interference Coordination(ICIC) scheme to mitigate the Co-Channel interference(CCI) in downlink Orthogonal Frequency Division Multiple Access (OFDMA) cellular system is presented. The proposed scheme combines a power control strategy, and uses the fractional frequency reuse to reduce the CCI. Simulation results show that the proposed scheme is superior to other existing schemes. It also shows that the scheme can greatly improve the throughput of the cell-edge users while guarantee system performance.
