Abstract

The invention discloses a spectrum sharing method based on a cognitive radio network. Based on a secondary user transmission controller and the traditional research on a physical relationship networkbetween sensing nodes, the physical relationship network and the communication data are combined to establish a social relationship network among the sensing nodes which is more suitable for information transmission and interference connection among the sensing nodes; a secondary user can be better assisted to complete spectrum sharing and spectrum sharing efficiency is improved; the social relation network is combined with the received environment information sensed by the sensing nodes to train the Q learning network to explore the optimal transmitting power, a Q learning model is established, the Q learning model is applied to determine the transmission power, the transmission power is used for information transmission, and high-efficiency transmitting power control is achieved. The invention also discloses a spectrum sharing device and equipment based on the cognitive radio network and a computer readable storage medium, 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, device, equipment and computer-readable storage medium based on a cognitive radio network. Background technique [0002] Cognitive radio technology (CR) proposes to improve spectrum utilization in an intelligent way, calculate wireless resource allocation and determine communication methods between devices according to user needs, and 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 to cognitive wireless networks is to use related technologies to allocate limited spectrum resources reasonably, so that secondary users (SU) can communicate without affecting the communication quality of service (QoS) of primary users (PU, also known as authorized u...
