| 摘 要： | 在长期演进项目的虚拟多输入多输出系统中，为了保证用户公平性的同时得到更大系统容量，在分析移动自组织网络和虚拟多输入多输出系统模型的基础上，提出了一种长期演进项目中基于移动自组织网络的虚拟多输入多输出配对算法。仿真结果表明，该算法得到的系统吞吐量是单输入多输出系统的3倍多，是随机配对策略的2．5倍，相比正交配对策略也平均提高了20％。同时在用户的公平性方面，还保证了低吞吐量用户的公平性。

| Abstract: | In order to get greater system capacity while guarantee the users＇ fairness in the Virtual MIMO （Multiple Input Multiple Output）system of LTE（Long Term Evolution）, we proposed an ad hoe network based on virtual MIMO pairing algorithm after researching the system model of ad hoe networks and virtual MIMO. And the simulation results showed that the system throughput of this algorithm is 3 times higher than SIMO system, 2.5 times higher than random pairing strategy, and increased by 20 percentage points compared to the orthogonal pairing strategy. In addition, on the fairness of the user, it also guarantees the fairness of the low throughput users. |
