| 摘 要： | 依据无人机信道快速时变的相关参数，设计了信道估计所需的时频二维插入导频图案，利用最小均方误差准则，采用维纳滤波器，实现了无人机时频二维信道估计。通过性能分析和数值仿真可以看出，基于Wiener滤波MMSE准则设计时频二维信道估计不仅可以提高无人机信道的精度，同时还可以保证信道的鲁棒性能。

| Abstract: | According to the related parameters of the unmanned aerial vehicle （UAV） ＇ s fast time-varying channel, the time-frequency pilot pattern, which is needed during channel estimation step, is designed. By adopting Wiener filter, UAV time-frequency two-dimension channel estimation is realized, which is based on MMSE. It is concluded that time-frequency two-dimension channel estimation not only improves the UAV channel accuracy, but ensures the robustness of the channel. |
