全频率复用的OFDMA系统中,小区间干扰严重降低了整个系统,特别是小区边缘的频谱效率。文中考虑了多小区放大转发系统下行链路的资源管理,须联合优化用户调度、载波和功率的分配,并设计了一个分布式的资源分配算法,算法基于本小区局部信息分步完成用户调度和功率控制,小区之间只需要较少的交互信息。仿真结果表明,文中算法较传统算法具有更好的系统性能。 OFDMA system with full frequency reuse, inter-cell interference severely reduces the spectral efficiency of the entire system, especially at the cell edge. Considering the downlink resource management of multi-cell amplification and forwarding system, user scheduling, carrier and power allocation should be jointly optimized and a distributed resource allocation algorithm is designed. The algorithm performs user scheduling and step by step based on the local information of the cell Power control, only need less interactive information between cells. Simulation results show that the proposed algorithm has better system performance than traditional algorithms.
