摘要
在认知无线电系统中,动态频谱分配是决定能否充分高效利用有限频谱的关键。文中建立起网络拓扑模型,分析了基于图论着色模型的动态频谱分配技术的发展过程、研究现状。并讨论了其未来的研究方向,主要是在算法改进上。
In the cognitive radio system,it is the key that the dynamic spectrum allocation decides the full and effective utilization of limited spectrum.In the article,established a network topology model,analyzed dynamic spectrum allocation process of development,the research present situation based on the gragh theory model.And discussed its future research directions,the main improvement is in algorithm.
