| 摘 要： | 首先,研究了MIMO空时分组编码(STBC)在平坦衰落信道下的应用以及相应的信道估计技术,并通过计算机仿真分析了STBC的性能以及信道估计对其性能的影响;接着,针对对流层散射信道特性,建立对流层散射信道的MIMO信道模型;最后,采用SC-FDE技术对抗对流层散射信道具有的频率选择性衰落,并仿真了该系统的性能,为STBC在对流层散射中应用奠定了基础。

| Abstract: | In the research,the application of MIMO space time block coding（STBC）in flat fading channel and corresponding channel estimation technology are studied first.Then,based on the characteristics of Troposcatter channel,the MIMO channel model of Troposcatter channel is established.Finally,SC-FDE technology is used to resist frequency selective fading,and the performance of the system is simulated.The research settles foundation of the application of STBC in Troposcatter system. |
