  • 1) 在本文中,统计信道信息(S-CSI)是指用信道的统计信息来描述信道特征,比如衰落分布类型、平均信道增益等特征参数;瞬间信道信息(I-CSI)则是指实时反映当前信道状态的参量。
  • 2) 本文研究的是中继工作在半双工模式的情况,同样,所提出的H-PAS功率分配策略也同样适用于当中继工作在全双工(Full-Duplex, FD)模式的场景。
  • 3) 对于功率域的非正交多址接入系统而言,就上行链路来说,一般认为质量好的信道为强信号并且在接收端被先解码;而对于下行链路来说,一般认为质量好的信道为弱信号并且在接收端被后解码。

  • 摘要: 针对基于非正交多址接入(NOMA)技术的中继通信系统,在兼顾系统性能与计算复杂度的基础上,该文提出一种结合统计信道信息(S-CSI)和瞬时信道信息(I-CSI)的混合功率分配策略(H-PAS)来有效实现上述折中。仿真结果表明,NOMA方案在H-PAS策略下,一方面比单纯利用S-CSI时的传统正交多址接入技术具有更高的频谱效率;另一方面在和速率差别不大的情况下,又比单纯利用I-CSI时的NOMA方案具有更低的信令开销和计算复杂度。
