| 摘 要： | 提出传输策略选择结合资源分配的迭代算法，证明其收敛性。进一步将算法简化为顺序进行的三步：子信道指配，传输策略选择和中继的发射功率分配，源的发射功率分配。仿真结果表明，所提资源分配迭代方案和简化方案的频谱效率性能均优于已有的两种资源分配方案，简化方案更适合实际应用。

| Abstract: | This paper proposed an iterative algorithm for resource allocations in OFDM relay systems, whose convergence has been proved. The simplified algorithm is executed in three ordered steps: first, subchannel assignment; second, transmission strategy selection and transmit power allocation at the relay; third, transmit power allocation at the source. Simulation results show that both the iterative and simplified algorithms outperform the two existing resource allocation schemes. The simplified one is more suitable for practical applications. |
