摘要

研究了OFDM下行接入系统中多用户的子载波分配问题。我们研究了在(i)实现用户之间的吞吐量公平，(ii)满足用户应用程序指定的可容忍延迟要求以及(iii)实现更高系统容量之间提供不同程度权衡的分配方案。通过仿真结果对各子载波分配方案的性能进行了评价。

Subcarrier allocation schemes for multiuser OFDM systems

We consider the problem of subcarrier allocation to multiple users in a downlink OFDM access system. We study allocation schemes that provide varying degrees of tradeoff between (i) achieving throughput fairness among users, (ii) meeting tolerable latency requirements specified by the user applications, and (iii) achieving higher system capacity. The performance of the subcarrier allocation schemes is evaluated through simulation results.
