Abstract

Abstract:

In high-dimensional wireless multi-user communication networks， there is a problem of unreasonable spectrum resource allocation， which leads to uneven network load and unstable communication quality. Traditional spectrum resource allocation methods can not respond to dynamic changes in user needs in real time， resulting in low utilization efficiency of spectrum resources. Therefore， a dynamic allocation algorithm for spectrum resources in high-dimensional wireless multi-user communication networks was proposed. By determining the dynamic allocation program of spectrum resources， while considering the goals of communication network load balancing and communication quality， a dynamic allocation objective function of spectrum resources was constructed， and its constraint conditions were explained. An improved genetic algorithm was introduced to solve the objective function and the optimal solution for dynamic allocation of spectrum resources was obtained. The experimental results show that the maximum spectrum resource utilization rate obtained by the proposed algorithm reaches 95%， and the spectrum resource allocation results are consistent with the actual results， fully confirming that the proposed algorithm has better spectrum resource allocation performance.

Key words: spectrum resources, user needs, network performance, high-dimensional wireless multi-user communication network, dynamic allocation
