摘　　要：基于单载波频分复用系统,提出一种应用于动态子载波分配方案的算法。在动态分配过程中,利用约束条件实现信道资源对各用户终端的公平分配,以此完成比例约束算法设计,并对其进行简化。实验结果表明,该算法能在提升系统总容量的同时保证公平性,其简化算法具有较好的分配性能和较低的计算复杂度。In this paper, a proportional rate constraints algorithm based on single carrier frequency division multiple access system, used for dynamic subcarrier allocation is proposed. The proposed algorithm utilizes appropriate allocation constrains to achieve the channel capacity resources allocation fairness for each user, thereby realizing the design of proportional rate constraints algorithm. On this foundation, a simplified algorithm is also proposed. Experimental results show that the algorithm can effectively improve the system capacity and guarantee the fairness, its simplified algorithm have good distribute performance and low calculation complexity.
