Abstract

The present invention discloses a channel predicting method and apparatus in a communication network comprising a time varying wireless channel. The channel predicting method comprising: determining a prediction strategy; selecting a certain number of channel samples from candidate channel samples each corresponding to one symbol in time domain in accordance with the prediction strategy; determining prediction weights in accordance with the prediction strategy and statistical properties of the time varying wireless channel; and weighting the selected channel samples with the determined prediction weights to obtain a predicting channel sample as a prediction result.
