The invention discloses a spectrum sharing method based on a cognitive radio network. Based on a secondary user transmission controller, on the basis of the traditional research on the physical relational network between sensor nodes, it combines the physical relational network and the establishment of communication data to obtain a more efficient The social relationship network between sensor nodes that combines information transmission and interference between sensor nodes can better assist secondary users to complete spectrum sharing and improve spectrum sharing efficiency. The perceived environmental information trains the Q-learning network to explore the ability of the optimal transmission power, establishes a Q-learning model, applies the Q-learning model to determine the transmission power, and uses the transmission power for information transmission to achieve efficient transmission power control. The invention also discloses a spectrum sharing device, equipment and computer-readable storage medium based on the cognitive radio network, which have the above beneficial effects.
Description
technical field [0001] The present invention relates to the technical field of cognitive radio and the technical field of spectrum allocation, and in particular, to a spectrum sharing method, apparatus, device and computer-readable storage medium based on a cognitive radio network. Background technique [0002] Cognitive radio technology (CR) proposes to improve the utilization of spectrum in an intelligent way. It can calculate the allocation of wireless resources and determine the communication mode between devices according to user needs, so as to provide users with wireless resources and services that best meet their communication needs. A network composed of multiple CR-capable devices is called a Cognitive Radio Network (CRN). The key of cognitive wireless network is to use related technologies to reasonably allocate limited spectrum resources, so that the secondary user (SU) can communicate with the primary user (PU, also called authorized user) without affecting the ...
