Power Allocation for Wireless Networks to Reduce Inter-Cell Interference

Abstract

This paper describes about the optimized power allocation process for next generation OFDMA wireless network. In order to achieve optimal power allocation to the edge cell and center cell users, the proposed scheme consists of power allocation process with QAM modulation technique. This technique reduces the inter-cell interference (ICI) and the path loss of the radio resource by implementing the greedy power algorithm .This achieves a better throughput than state of the art techniques. The radio resources are distributed to the edge cell users with a higher order form of QAM, thereby reducing the fading and shadowing effects of the signal. Hence this power allocation process and QAM results in better performance to the edge cell and center cell utilizers with power retention of the radio resources .
