Dynamic Spectrum Allocation based on Cognitive Radio
Xiao Ling Yan, Qijun Song, Hongshun Zhang, Lulu Shao · 2009
To settle the contradiction between scarce radio spectrum resource and the exigent requirement, effective methods of dynamic spectrum allocation are proposed in cognitive radio system. In this paper, game theory model and graph-coloring model are analyzed, which can improve spectrum efficiency and solve the deficiency of spectrum resource.
