Multi-Access Interference Mitigation Using Multi-Level Power Control Algorithm in OFDMA Cellular System

Abstract

Power control is an efficient technique to mitigate the effect of interference, combat the Near-Far problem and conserve the battery life. Thus, an effective implementation of different power control algorithms in cellular radio communication systems can offer a significant improvement in the Quality of Service (QoS) to all the users. In this paper, increasing system capacity and using frequency reuse concept at the same cell will be investigated. That is because of the use of a new Multi-Level Power Control (MLPC) Algorithm to enhance the network performance by the ability of using the available channels in an efficient way and mitigate the interference at the same cell. System simulations are used to compare the performance of the proposed algorithm with the traditional one which done using dense Monte Carlo simulations. In addition, the effects of some system model parameters are discussed.
