Abstract

Considering practical constraints in the single-carrier frequency division multiple access system, this paper proposes a jointed resource allocation and multiuser pairing algorithm with low complexity. It initially schedules the first user and carries out resource allocation and then selects the second and following pairing users in turn. Meanwhile, the proportional fair criterion is considered independently in the scheduling process for every pairing user. The simulation results show that, excluding its considerably lower complexity, the proposed algorithm has better throughput and fairness than the existing algorithms.
