5 G Research on Path Optimization System of Radio Resource Management and Distribution in the Context

In recent years, with the rapid growth of wireless communication services and the increasing requirements for the transmission rate and quality of wireless comunication information, the available spectrum resources have become increasingly scarce. Therefore, how to make full use of spectrum resources has become a key issue in the development of wireless communication technology. As a key technology that can effectively improve spectrum utilization, cognitive radio has become a new hotspot in wireless communication research. In order to solve the problem that most cognitive radio scenarios have multiple primary users with strong activity in real life, a multi power cognitive access strategy based on the activity of multiple primary users is proposed. The mathematical expression of cognitive system throughput under the strategy is derived theoretically, and the computer simulation is carried out. The results show that the proposed cognitive access mechanism enables cognitive users to choose the optimal authorized channel for transmission, and adaptively adopts multi power access strategy, which not only reduces the interference to authorized users, but also maximizes the capacity of cognitive system.
