| 摘 要： | 经典的信道估计为线性插值,而信道的多普勒频偏体现了信道参数变化的快慢,因此信道插值的参与点数可以根据多普勒频偏进行动态调整.该文据此提出了基于多普勒频偏估计的自适应多时隙加权平均(WMSA)信道估计算法,有效提高了信道估计精度.

| Abstract: | The classical channel estimation method is linear interpolation, and the variation rate of the channel corresponds to its maximum Doppler shift. Hence, the interpolation length can be decided by the estimated Doppler shift. An adaptive weighted multi-slot average channel estimation method is thus proposed to improve channel estimation accuracy. |

| Keywords: | Doppler-shift channel estimation weighted multi-slot average |
