摘要 OFDMA是下一代无线通信系统中在下行链路上实现大容量通信的一种有前途的技术,其中的关键技术之一是在共享信道的用户间公平合理地分配子载波和功率。分析了功率约束下系统最大吞吐量的实现方法,提出了一种基于有限反馈的资源公平调度算法,这种算法具有系统所需反馈信息量少、用户间公平性好等性能。 Orthogonal frequency division multiple access (OFDMA)is a promising technique for achieving high downlink capacities in next generation wireless communication system. A key issue in OFDMA is the allocation of the sub-carriers and power among users sharing the channel. The realization of the maximum system throughputs under power limitation was analyzed, and a fair resource scheduling algorithm based on limited feedback proposed. Simulation results show that the proposed algorithm needs only a little feedback information and has fairness among users.
