[Abstract]:The rational allocation of spectrum resources in mobile communication networks can effectively promote the integration and management of wireless communication network resources.In the management of spectrum resource allocation, it is necessary to calculate the basic probability allocation value of spectrum resource in mobile communication network, determine the total number of bits allocated by each user, and complete the resource allocation management.The traditional method firstly allocates power to subcarriers and updates the resource allocation mechanism, but neglects to determine the total number of bits allocated by each user, which leads to the unsatisfactory management effect of resource allocation.A spectrum resource allocation algorithm for mobile communication networks based on evidence theory is proposed.Firstly, the multi-user power adaptive resource allocation model is constructed based on Perron-Frobenius theory. The evaluation index of delay, rate and packet loss rate is set up by using evidence theory, and the basic probability allocation value of spectrum resource in mobile communication network is calculated.The basic probability allocation value of spectrum resource in mobile communication network is calculated and the total number of bits allocated by each user is determined. The spectrum resource allocation of mobile communication network is completed.The experimental results show that the proposed algorithm has high resource allocation accuracy and lays a foundation for improving the utilization of communication resources in mobile networks.
