摘要
传统的频率分配方法通常基于固定的规则和算法,导致无线通信波束频率分配收敛性差,为此提出一种基于粒子群算法的无线通信波束频率分配方法.首先确定波束频率干扰指标,用于判断不同频率之间的干扰情况;其次根据选取的指标制定频率分配约束条件,提高频率利用率;最后利用粒子群算法寻求波束频率划分最优解,并评估分配代价,实现无线通信波束频率分配.实验结果表明,设计方法的收敛性较好,可以更快地找到最优解,即频率分配方案,具有较好的实际应用价值.
Abstract
Traditional frequency allocation methods are usually based on fixed rules and algorithms,which leads to poor convergence of wireless communication beam frequency allocation.Therefore,a method of wireless communication beam frequency allocation based on particle swarm optimization is proposed.Firstly,the interference index of beam frequency is determined to judge the interference between different frequencies.Secondly,according to the selected indicators,the frequency allocation constraints are formulated to improve the frequency utilization rate.Finally,the particle swarm optimization algorithm is used to find the optimal solution of beam frequency division,and the allocation cost is evaluated to realize the beam frequency allocation of wireless communication.The experimental results show that the convergence of the design method is good,and the optimal solution,namely the frequency allocation scheme,can be found faster,which has good practical application value.
