摘要
由于蜂窝移动通信网络中可用的频率资源是有限的,为了有效利用这些频率资源来满足不断增加的客户需求,因此获得一种较优的频率分配方法就显得非常重要。提出了一种改进的遗传算法,该算法采用了新的选择策略和交叉策略,并且在选择个体时还采用了精英保护机制。仿真结果表明,改进后的算法能够很好地解决频率分配问题。它有效地保证了种群中个体的多样性,而且不仅提高了算法的收敛率,还加快了收敛速度。
The available frequency resource in cellular mobile communication network is limited,and in order to meet the increasing demand of the client,a better frequency assignment method is of great importance.A modified genetic algorithm is proposed in this article,in which a new selection strategy and a new crossover strategy are adopted,including an elite protection mechanism in individual selection.The simulation result shows that the modified algorithm could effectively deal with the problem of frequency assignment,protect the diversity of individuals,improve convergence rating and convergence speed.
