针对正交频分多址接入解码转发(OFDMA-DF)中继上行链路通信系统,提出了一种基于比例速率公平约束的资源分配算法。新算法主要分为两个步骤:首先在假定平均功率分配下,按照速率约束比越小的用户越优先选择子载波和中继这一准则进行载波分配和中继选择;然后在此基础上进行子载波上的优化功率分配,并给出了功率分配结果。分析结果显示,新算法在获得较高系统容量的同时能很好地保证用户之间的公平性。
For orthogonal frequency division multiple access-based decode-and-forward(OFDMA-DF)relay uplinks communication system,a new algorithm with proportional fairness constraints of users’ rate was presented.The new algorithm was divided into two steps.Firstly,under equal power distribution,the user with the lowest proportional capacity had the option to pick which subcarrier and relay to use.Then,based on this basis,power allocation was optimized on subcarriers and the power allocation results were given.Analysis results demonstrate that the new algorithm can not only obtain high system capacity,but also guarantee fairness between users.
