摘　　要：为研究认知网络中的频谱切换判决问题,本文提出了一种基于模糊神经控制的切换判决算法。设计了模糊逻辑控制器,通过神经网络对隶属度函数和模糊推理规则进行自适应调整。仿真结果表明,本文提出的算法,可以降低切换比例和认知用户中断概率。To research the decision of spectrum handoff, a handoff decision algorithm based on fuzzy neural control is proposed. The fuzzy logic controller is designed. The modulate of the membership function and fuzzy inference rules are based on neural net. The simulation results show that, the algorithm proposed in this paper can reduce the spectrum handoff rate and the interruption rate.
