The invention discloses a random-linear-network-code (RLNC)-based back-off frequency spectrum prediction method in a cognitive radio (CR) network. With utilization of frequency spectrum predictability caused by RLNC introduction into a main user channel of cognitive radio and a prediction effect on a frequency spectrum by a hidden markov model, a back-off prediction method is introduced to carry out frequency spectrum state prediction at a next time slot. With the method, defects that frequency spectrum state is switched frequently and the spectrum hole can not be sensed easily in the traditional CR network and the reliability is low of the existing frequency spectrum prediction algorithm can be overcome. With introduction of back-off prediction method, the frequency spectrum state prediction at a next time slot is carried out by using the frequency spectrum predictability caused by RLNC introduction into the cognitive radio network and the prediction effect on the frequency spectrum by the hidden markov model, so that frequency spectrum prediction reliability is improved.
