CHANNEL ESTIMATION METHOD AND APPARATUS, AND DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2021/109639

A1

A channel estimation method and apparatus, and a device and a storage medium. The method comprises: determining an initial channel estimation according to a received time-domain training sequence and a local time-domain training sequence, and calculating the power of each diameter of the initial channel estimation; providing a channel estimation window of a set length in the initial channel estimation, and determining a noise threshold according to the power of an inner diameter of the channel estimation window and/or the power of an outer diameter of the channel estimation window; determining an effective diameter quantity according to the noise threshold and the power of each diameter of the channel estimation window; and selecting a diameter for the initial channel estimation according to the effective diameter quantity, to obtain a target channel estimation.
