脏纸编码的多用户MIMO-OFDM系统中的比例公平算法
摘要
针对脏纸编码的多用户MIMO-正交频分复用(OFDM)系统
提出了一种新的自适应资源分配算法。算法采用了邻域搜索的方式
在保证用户间速率比例公平的前提下使系统吞吐量最大化
获得了系统吞吐量和用户间公平性的良好折中。仿真结果表明
该算法在系统吞吐量损失较小的情况下
很好地满足了用户间速率的比例公平要求。
Abstract
A novel resource allocation algorithm was proposed for dirty-paper coded multi-user multiple-input multi-ple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems. The new algorithm can guarantee the proportional fairness among users while achieving large system throughput by local search. Simulation results show that the proposed algorithm provides great fairness among users
