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.

Key words: channel estimation, Doppler-shift, weighted multi-slot average
