摘要：
The embodiment of the invention discloses a method, device and computer program for denoising in channel estimation. The method comprises steps of: calculating a noise power value and a power value of each path in each user window based on a channel estimation result, the user window is referred to channel impulse response window corresponding to this user; calculating a denoising threshold factor based on the noise power value and the power value of each path in each user window; calculating a denoising threshold value based on the noise power value and the denoising threshold factor; and performing a denoising processing on the channel estimation result by using the denoising threshold value.
