摘要
认知无线电是可以感知外界通信环境的智能通信系统,其中的频谱分配技术是解决现在频谱资源匮乏、提高频谱利用率的一项热门研究。该文首先对认知无线电系统中基于图论着色的频谱分配模型及其数学符号描述进行介绍;然后对图论着色中的几种算法进行了详细研究并比较总结;最后简单阐述了现存的问题及其未来的发展趋势。
Cognitive radio is a intelligent communication system that can perceive external communication environment,in which the spectrum allocation technology solution is a popular research that can solve the question of spectrum resource depletion、improvement of frequency utilization.This paper firstly introduce the cognitive radio system based on the spectrum allocation of graph coloring model and mathematical symbols descriptions;Then the algorithms of graph coloring are studied and compared;Finally expounds the existing problems and the future trend of development briefly.
