摘要 针对认知无线电网络中的频谱分配问题,融合频谱的连续可用概率,提出了一种改进的分配模型,并基于频谱分配问题的NP特性,提出了一种基于极值优化的启发式智能求解算法。仿真实验表明:本算法能获得较好的频谱分配效果,有利于频谱资源的有效利用。 To study the spectrum allocation problem in cognitive radio network, an improved allocation model considering spectrum availability is proposed. An extreme optimization algorithm is proposed based on its NP features. Simulation results show that the proposed algorithm can get better spectrum allocation results and improve the spectrum usage.
