摘　　要：认知无线网络中,已有的频谱分配方案大多集中在比较广义的范围。设计了一种混合优化方案求解无线区域网络的频谱分配问题。给出了无线区域网的拓扑结构和分配模型,设计了求解问题的量子编码、观测算子,构造了一种改进的量子旋转门算子,实现了算法的并行实现机制。仿真结果表明,该算法具有可以获得较优的频谱分配性能。The existing spectrum allocation scheme is in a relatively broad range in cognitive radio networks. In this paper,the spectrum allocation of wireless regional area network is considered and a quantum evolutionary algorithm is designed to solve it. The topology and allocation model of regional area network network is given and some operators such as quantum coding, observation are designed. An improved quantum gate operator is constructed and a parallel implementation algorithm is achieved. Simulation results show that the proposed algorithm can obtain higher performance for spectrum allocation.
