| 摘 要： | 针对高速移动性,特别是在高速铁路的背景下,分析了高速移动条件下信道的特性,提出在单载波频域均衡技术(SC-FDE)的基础上,设计合理的帧结构对抗快速时变信道的影响,加入空间分集和频率分集获得分集增益,从而进一步对抗衰落。仿真结果表明,采用SC-FDE技术能够有效地支持分集接收,解决高速移动带来的信道快衰落问题,提高高速移动环境中的通信质量。

| Abstract: | For high-speed mobility,especially in the context of high-speed railway,the channel characteristics under the condition of high-speed mobile are analyzed firstly,the article,based on the SC-FDE,proposes the reasonable design of frame structure against the fast time-varying channel effects,and add spatial diversity and frequency diversity to obtain diversity gain against fading further.Simulation results show that SC-FDE can effectively support diversity reception,solve the channel fast fading caused by high... |
