| 摘 要： | 该文研究了低频通信中的时延估计问题。考虑在低频信道大气噪声干扰的条件下,对接收信号进行削波处理后,采用循环相关法进行多径时延估计。经过削波处理,该方法能准确地估计出低频通信的时延,并且其性能优于广义相关法。该文最后的计算机仿真结果验证了文中的结论。

| Abstract: | The problem of time delay estimation under the LF communication is investigated.Take into account the atmospheric noise and clipped received signal,the cyclic correlation method are used.After clipped,the method can estimate time delay exactly and the performance is better than the generalized cross-correlation method.The relevant conclusions are got and verified by the simulation result. |
