| 摘 要： | 提出了基于文化算法的认知无线电优化方法,以通断键控系统为例设计了待优化的多目标参数,利用文化算法的指导空间概念,加快目标参数优化速度。计算机仿真结果表明文化算法的收敛速度明显优于遗传算法,在进化代数明显少于遗传算法的情况下获得近似遗传算法的优化结果,这一特性适合于对实时性要求较高的认知无线电优化。

| Abstract: | The optimization cognitive radio based on cultural algorithm is proposed.The multi-objective parameters,which need to be optimized,are designed basing on OOK system.Optimization speed is accelerated by using the concept of the guiding space.Computer simulation results show that cultural algorithm convergence speed is superior to genetic algorithm.It can get similar results compared with genetic algorithm optimization but less evolution generations.This property is very suitable for demanding real-time optim... |
