| 摘 要： | 为解决认知无线电网络中认知用户、授权用户共存情况下的频谱分配问题，提出了一种基于潜在博弈的认知无线电频谱分配模型，该模型以最小化系统总干扰水平为目标，认知用户采用避免机会浪费的改进型策略动态调整规则进行频谱选择，经过有限改进路径快速收敛到博弈的纳什均衡点。在30个认知用户和2个授权用户共存的场景下进行仿真实验，算法以较快的收敛速度实现了频谱分配的目标，证明了模型及算法的可行有效。

| Abstract: | To solve the spectrum allocation problem in cognitive radio networks in case of the coexistence of cognitive users and authorized users,a cognitive radio spectrum allocation model based on potential game is proposed.The aim of the model is to minimize the total interference of the system.The cognitive users employ an improved dynamic policy adjustment rule(which avoids the opportunities wasting) to conduct the selection of frequency spectra,and converge to the Nash equilibrium through finite improvement pat... |
