| 摘 要： | 频谱分配技术是认知无线电的关键技术之一,为适应认知无线电系统的时变特性,频谱分配算法必须有较快的收敛速度。在干扰温度模型下,提出一种基于Kuhn-Munkras算法的认知无线电频谱分配策略。该策略利用Kuhn-Munkras算法可以实现最佳匹配并且收敛速度快的特性,根据不同的用户在不同信道上所产生的效益的差异性,实现认知用户和信道的最佳匹配。仿真表明,基于Kuhn-Munkras算法的频谱分配在性能上优于传统的配对算法和greedy算法。

| Abstract: | Spectrum allocation is the key technology for cognitive radio,the algorithm for spectrum allocation must converge rapidly,thus to adapt itself to the cognitive radio system.A spectrum allocation strategy for cognitive radio network based on Kuhn-Munkras algorithm under the a interference temperature model is proposed in this paper.This strategy utilizes the characteristic of Kuhn-Munkras algorithm achieves the optimal matching and obtains convergence rapidly,thus realizing optimal matching between secondary... |
