| 摘 要： | 随着移动通信的高速发展,传统的连续频谱分配策略已经无法满足当前用户的带宽需要。LTE-A建议采用频谱聚合技术,通过聚合离散的频谱碎片,解决用户对带宽资源的需求,动态地改善频谱效率。针对两跳中继协作通信系统,综合考虑频谱利用率和协作速率双重因素,提出了一种基于离散频带的中继协作网络中的频谱聚合方法。仿真结果表明,与传统的连续分配方法相比,该方法可以大幅度地提高系统吞吐量,改善频谱利用率,从而满足用户日益增长的带宽需求。

| Abstract: | With the rapid development of mobile communications,traditional continuous spectrum allocation cannot meet users' bandwidth needs.Through aggregating discrete spectrum pieces,spectrum aggregation,which is recommended in LTE-A,can satisfy users' bandwidth demands,meanwhile dynamically improve spectrum efficiency.In two-hop relay cooperative system,considering both spectrum efficiency and cooperative rate,a spectrum aggregation algorithm in relay cooperative network based on discrete bands has been put forwar... |
