Document Type and Number:
WIPO Patent Application WO/2022/222116
Kind Code:
A1
Abstract:
Embodiments of the present application provide a channel recovery method and a receiving end device, which can perform channel recovery on the basis of a neural network, and improve channel recovery performance, thereby improving data recovery and channel feedback performance. The channel recovery method comprises: a receiving end device receives a pilot signal and a data signal sent by a sending end device; the receiving end device performs channel correlation feature extraction on target information by means of a first neural network to obtain a target feature map, wherein the target information comprises the data signal and the pilot signal, or the target information comprises the data signal and a pilot position channel determined on the basis of the pilot signal; and the receiving end device performs channel recovery processing on the target feature map and the pilot position channel by means of a second neural network to obtain the recovered channel information.
