摘要：

The improved partial proportional fair (IPPF) algorithm for OFDMA relay system is proposed, aiming at solving the fairness scheduling problem. Subcarriers are distributed to all users in both two sub-timeslots. And the relay users are regarded as two users in the subcarrier scheduling for the second sub-timeslot, so as to balance the data rates of all users. The IPPF algorithm achieves a better balance between the system throughput and user fairness, compared with the partial proportional fair (PPF) algorithm and the two-hop proportional fairness (THPF) algorithm, from the simulation results. Since the PPF algorithm only ensures the user fairness of the second sub-timeslot, and the system with THPF suffers a big throughput loss.
