提出1种可应用于正交频分复用多址(OFDMA)中继网络的分布式资源分配算法.基于将模型描述为基站与中继的非合作功率分配博弈(RNCPAG),设计出2种效用函数,并以最大化效用函数为准则,证明在总功率受限的约束下,该算法存在并收敛于唯一的纳什均衡点.研究表明,同传统的平均功率分配算法相比,分布式博弈算法以牺牲少量的迭代步数为代价,获得更高的系统容量和资源效率.
This paper presents a distributed resource allocation algorithm that can be applied to Orthogonal Frequency Division Multiple Access (OFDMA) relay networks.Based on the model described as RNCPAG, two kinds of schemes are designed The utility function is maximized and the utility function is used as the criterion to prove that the algorithm exists and converges to the only Nash equilibrium under the constraint of the total power.The research shows that compared with the traditional average power allocation algorithm, The algorithm gains higher system capacity and resource efficiency at the expense of a small number of iterations.
