SC-FDMA动态子载波分配算法
Dynamic Subcarrier Allocation Algorithm for SC-FMDA
摘要
Abstract
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.关键词
