CHANNEL ESTIMATION METHOD AND DEVICE

摘要

A channel estimation method, comprising: a channel estimation device employs a two-dimensional channel estimation method and utilizes the channel estimate of an original pilot frequency to conduct channel estimation on an encrypted pilot frequency, so as to obtain the channel estimate of the encrypted pilot frequency; the channel estimation device employs a one-dimensional channel estimation method and utilizes the channel estimate of the encrypted pilot frequency to conduct channel estimation on all resources, so as to obtain the channel estimates on all resources.
