摘要/Abstract

摘要：

针对高维无线多用户通信网络中因频谱资源分配不合理导致网络负载不均衡、通信质量不稳定，传统的频谱资源分配方法无法实时响应用户需求的动态变化，从而导致频谱资源的利用效率不高的问题，提出了高维无线多用户通信网络频谱资源动态分配算法。通过确定频谱资源动态分配程序，同时兼顾通信网络负载均衡目标与通信质量目标，构造频谱资源动态分配目标函数，并阐明其约束条件。引入改进遗传算法对目标函数进行求解，获取频谱资源动态分配最优方案。实验表明，应用本文算法获得的频谱资源利用率最大值达到了95%，频谱资源分配结果与实际结果一致，充分证实了本文算法具备更优质的频谱资源分配性能。

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.
