Title
A fair MaxSNR scheduling scheme for multiuser OFDM wireless systems
Abstract
MaxSNR scheduling is acknowledged as the reference resource allocation for multiuser OFDM wireless networks. Well adapted to the wireless environment, MaxSNR opportunistically considers the channel state and fights the multipath fading negative effects. Taking advantage of multiuser diversity, MaxSNR scheduling is well-known for maximizing the global cell throughput. However, throughput maximization is made at the expense of fairness. Indeed, severe fairness deficiencies appear especially when mobiles experience unequal path loss due to unequal position. In this paper, we propose to solve this fairness issue with a modified MaxSNR scheme that introduces distance compensation factors while keeping the original MaxSNR system throughput maximization properties. Simulation results show that this well-balanced resource allocation outperforms other existing scheduling schemes and jointly provides both high system throughput and high fairness.
