| 摘 要： | 通信的主要任务就是在接收的信号中恢复发送信号。这就需要知道信道的冲击响应。因此信道估计是通信系统中的重要一环。文章介绍了一种在发送序列之上叠加周期训练序列，利用周期训练序列来进行信道估计的方法，并提出了基于叠加周期训练序列的信道阶数估计方法。并对其进行了仿真分析。 |
| 关 键 词： | 信道估计 叠加序列 阶数判定 |

| Abstract: | The main objective of communication is to recover the information from the transmitter at the receiver. It needs knowing the channel impulses. So the channel estimation is the important part of the shortwave communication. In this paper, a method to perform channel estimation is introduced, which use a periodical training sequence added to the information sequence And a new method is proposed for determining the steps of the channel. At last, it gives the simulation results. |
| Keywords: | channel estimation superimposed training steps determine |
