Analysis of weigthed proportional fair resource allocation for uplink OFDMA

We investigate in this paper the resource allocationproblem in an uplink OFDMA multiuser system. We focus onthe Proportional Fairness approach which aims to maximizethe system throughput and while ensuring fairness betweenusers. In this paper, we propose a Weighted Proportional Fairalgorithm for resource allocation that introduces prioritiesbetween users to better exploit good channel conditions in thecell center. We also perform a theoretical analysis to compareboth standard and weighted proportional fair algorithms.Simulation results, compared to existing algorithms, showthat the proposed algorithm approaches the max sum rateupper bound but still maintains sufficient fairness between users
