Adaptive adjustment spectrum sensing method and device

The invention provides a self-adaptive adjustment spectrum sensing method and device, and the method comprises the steps: obtaining the sensing times in the current super-frame time based on the pre-obtained authorized user data, and the authorized user data comprises the historical activity data or initial loading data of an authorized user in at least one super-frame time on a corresponding pre-selected spectrum; performing prediction according to the authorized user data to obtain a predicted active probability; according to the predicted active probability and the number of times of perception, obtaining a predicted perception period and a predicted perception duration; and performing spectrum sensing on the spectrum based on the predicted sensing period and the predicted sensing duration, and performing communication by using the spectrum when an authorized user on the spectrum is in an idle state based on a spectrum sensing result. According to the method, the sensing period and the sensing duration are
