<p>Disclosed are a channel estimation method and device. The method comprises: according to the least square estimation of a pilot frequency, calculating linear amplitude-phase interpolations of an interpolated position in the time direction and the frequency direction respectively; and according to the linear amplitude-phase interpolations of the interpolated position in the time direction and the frequency direction, synthesizing a channel estimation of the interpolated position. By means of the present invention, according to the least square estimation of the pilot frequency, by calculating linear amplitude-phase interpolations of an interpolated position in the time direction and the frequency direction respectively, and synthesizing a channel estimation of the interpolated position, the problem in the related art that the linear interpolation method may cause an exceptional amplitude fluctuation of linear interpolated values is solved, and an optimized channel estimation method is provided in turn, thereby preventing the exceptional fluctuation of interpolated values.</p> |
