Abstract

The embodiment of the present application discloses a channel prediction method, device, and computer storage medium. The method includes: processing historical channel state information through at least one channel predictor to obtain at least one predicted channel; processing at least one predicted channel to obtain The processed prediction channel. In this embodiment of the present application, the predicted channel can be processed to realize channel prediction and improve the accuracy of channel prediction.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a channel prediction method, device and computer storage medium. Background technique [0002] In a wireless communication system, the transmitter is used to send signals, and the receiver is used to receive signals from the transmitter. The wireless link between the transmitter and the receiver is called a wireless channel. Channel estimation refers to estimating the response of a wireless channel between a transmitting antenna and a receiving antenna. Due to the randomness of the real channel environment, the channel estimation algorithm calculates the channel state information (Channel State Information, CSI) based on the measurement signal at the current moment, and does not take the channel coefficient at the historical moment into consideration. [0003] Based on this, a channel prediction method is proposed. Channel prediction refers to predicting fut...
