| 摘 要： | 针对OFDMA下行链路发送端只能获得部分信道信息的情况,提出了一种基于部分信道信息的资源分配算法.该算法通过建立部分信道信息模型,考虑传输的中断概率,保证分配的数据速率、子载波等资源与真实的信道条件匹配.仿真结果表明,该方法实现了较好的多用户分集增益和实际吞吐量性能.

| 关 键 词： | 资源分配 正交频分复用 中断概率 多用户分集 部分信道信息 |

| Abstract: | Aiming at the problems of only partial channel information which could be got in transmitter of downlink,a resource allocation algorithm based on partial channel information was presented.In this algorithm,outage probability and partial channel model was considered,subcarriers and rate allocated matched true channel.Computer simulation showed that it gained diversity benefits and goodput performance. |

| Keywords: | resource allocation orthogonal frequency division multiplexing outage probability multiuser diversity partial channel information |
