| 摘 要： | 针对两跳OFDMA Relay网络的特点，将单跳无线网络中3种经典调度算法(轮循(RR)算法、最大载干比(MaxC/I)算法和正比公平(PF)算法)推广到两跳场景中，得到适合两跳中继网的3种二级调度算法E-RR、E-MaxSNR、E-PF。仿真分析表明，3种调度算法的性能比原有算法有较大提升，E-RR能获得好的用户公平性，E-Max C/I可以获得最大的系统吞吐量，E-PF在用户公平性和系统吞吐量间可以取得良好的折中。

| Abstract: | Aiming at the characteristics of two-hop OFDMA Relay network, classical packet schedule algorithms(RR, MaxC/I, PF) are extended to two-level schedule algorithms(E-RR, E-MaxSNR, E-PF). Simulation results indicate that the three new two-level schedule algorithms have good system performance compared with the former algorithms. E-RR obtains good performance on user fairness, E-MaxSNR has maximum system throughput and E-PF achieves tradeoff between system throughput and user fairness. |
