Efficient MFR Scheduler Algorithm for OFDMA Cellular System

In a multi cell scenario, co channel and adjacent channel interferences occur and degrade the performance of cellular networks particularly of the edge users. In this paper, a fusion algorithm is proposed for cancellation of Inter cell Interference and resource allocation. This algorithm is based on Energy Efficiency and capacity. The main objective of this algorithm is considering the edge user equal to center user. Due to transmission through relay node, energy efficiency will be high for edge users. Energy efficient algorithm is proposed for users and it provides better cell edge efficiency and fairness. In this method, inter cell interference (ICI) is cancelled by modified frequency reuse (MFR) technique. After cancellation of ICI, the resources are allocated to the user equipment based on scheduling metric and transmitted energy per bit. The proposed method is compared with the previous techniques like maximum carrier to interference ratio (MCI) and round robin technique (RR). Performance metrics like spectral efficiency, SINR, cell energy efficiency, capacity and fairness are analyzed.
