摘　　要：针对对流层散射信道的频率选择性,提出了一种基于训练序列的单载波空时分组编码(Space Time Block Code,STBC)系统的信道估计算法。首先建立了单载波空时分组编码系统的系统模型,确定了发送分组结构和接收技术;接着提出了信道估计算法,并讨论该算法中Chu序列的最优性;最后通过仿真分析了信道估计算法的性能和效率。In this paper,a training sequence-based single carrier space time block code channel estimation method for frequency selective troposcatter channel is proposed. First,the single carrier space time block code system model is built, the construction of trans- mit group is confirmed. Then,the channel estimation algorithm is proposed, and the optimization of CHU sequence in the algorithm is discussed. Finally, the performance and effectiveness of the proposed algorithm is analyzed by simulation.
